How is water pump power calculated?

Pump Power calculation Formula: Pump Power P(kW) = q(m3/hr) x ρ(kg/m3) x g(m2/s) x h(m) x p(Pa) / 3600000. The same way pump power in horsepower formula can be written as, Pump Power P(HP) = q(m3/hr) x ρ(kg/m3) x g(m2/s) x h(m) x p(Pa) / 2685600. Also above pump power is required to lift the liquid to head meters.

How do you calculate pumping rate?

The formula for determining the flow rate is gallons drawn down (that were measured above), divided by the seconds required for recovery, then multiplied by 60: (Gallons / Seconds) x 60 = Gallons per Minute (GPM) flow rate..

How do you calculate pump capacity?

To calculate the hydraulic power of a pump:

1. Multiply the discharge Q with the differential head H .
2. Multiply the product with the density of the fluid and the acceleration due to the gravity constant.

How do you calculate well pressure?

Well Control Course Equations Part 1

1. Pressure (psi) = Force (lb) / Area in Square Inch (in 2)
2. Mud Gradient ( Psi/ft ) = Mud weight ( PPG) x 0.052.
3. Hydrostatic Pressure (HP) = Mud weight (PPG) x 0.052 x TVD (ft)
4. Bottom Hole Pressure (BHP) = Hydrostatic Pressure (HP) + Surface Pressure (SP)

How is well water flow rate measured?

The formula for determining well flow rate is: (Gallons drawn) divided by the (number of seconds timed for the pump cycle), then multiplied by 60 equals the gallons per minute (GPM) that your pump produces.

What is a good flow rate for a well?

The Water Well Board and the New Hampshire Water Well Association, a group of private professionals associated with the well water industry, both recommend a flow rate of 4 gallons per minute for a 4 hour period. That’s equivalent to 960 gallons of water flowing steadily for 4 hours.

What is 3960 pump calculation?

The “3,960” is a horsepower expressed in pump terminology. This pump would burn 18.1 horses or 13.5 kilowatts (1-Hp = . 746-kw).

What are the effects of pumping a well?

Effects of Pumping Wells. Cones of Depression: Pumping at a well, or at a wellfield, pulls water toward the well from all directions – in other words, it induces radial flow. In doing so, pumping causes a reduction in hydraulic head, known as drawdown, and generates a cone- or funnel-shaped depression (Figure 35).

Why do wells produce only a fraction of their potential?

Most wells produce only a fraction of their potential because standard pressure tank systems only withdraw water from the well when someone is using water and so allows them to be at rest most of the time.

What is a conventional well pumping system?

Conventional pumping systems remove water from the well until the end use is satisfied, whether that end use is your shower or a storage tank that needs filling. In a slow or low yield well, the water column is constantly being drawn down when demand for water exceeds the rate at which it flows into the well.

Why are the well pumps delivering more GPM now?

First, the well pumps are delivering more gpm now because the wells are running nearly full and they do not have to lift the water from 800 feet. Second, the well yield is increased because he is no longer dewatering the area and reducing the well’s interface with the aquifer.

What is multiple frequency radar?

This mobile radar consists of three polarimetric Doppler subsystems operating at Ku-band (13.4 GHz), Ka-band (35.6 GHz) and W-band (94.92 GHz). This combination of frequency bands allows measurement of a wide range of atmospheric targets ranging from weakly reflecting clouds to strong precipitation.

How multiple frequency CW radar can be used to measure the range of a moving target?

CW radar can measure the instantaneous rate-of-change in the target’s range. This is accomplished by a direct measurement of the Doppler shift of the returned signal. The Doppler shift is a change in the frequency of the electromagnetic wave caused by motion of the transmitter, target or both.

What is CW radar explain the operation of CW radar with neat block diagram?

Block Diagram of CW Radar CW Transmitter − It produces an analog signal having a frequency of fo. The output of CW Transmitter is connected to both transmitting Antenna and Mixer-I. Local Oscillator − It produces a signal having a frequency of fl. The output of Local Oscillator is connected to Mixer-I.

What are various applications of CW radar?

A continuous wave (CW) radar has been used for the detection and classification of people based on the Doppler signatures they produce when walking. When humans walk, the motion of various components of the body including the torso, arms, and legs produce a very characteristic Doppler signature.

What is the main advantage of a CW radar?

The main advantage of CW radar is that energy is not pulsed so these are much simpler to manufacture and operate. They have no minimum or maximum range, although the broadcast power level imposes a practical limit on range.

How can a continuous wave radar system measure the range of the target?

For a CW radar to be able to measure range too, the transmitted signal must be marked on the time axis. Such marking is usually implemented through periodic phase or frequency modulation. The modulation also helps to separate the target-reflected signal from the directly received signal.

What is CW RF?

Both continuous-wave (CW) (left) and pulsed (right) signals are used throughout RF/microwave systems, such as communications and radar equipment, with differences in performance and behavior. An FMCW radar system, with its continuous measuring signals, is capable of good range resolution, often as fine as 0.5 m.

What are the advantages and limitations of CW radar?

Benefits or advantages of CW Radar ➨It is used for wide variety of applications as listed above. ➨It transmits power with lower value and hence does not interfere other wireless devices. ➨It is simple in construction. ➨The performance of CW radar is not affected due to stationary targets.

Which circuit uses frequency hopping?

1 is known as Bluetooth [7], which uses Frequency Hopping Spread Spectrum (FHSS) [5]. In FHSS the message signal is transmitted by rapidly switching among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver.

Is frequency hopping used in GPS?

The Global Positioning System (GPS), another alleged part of Lamarr’s legacy, has always used direct sequencing. Although the early 2G cellular network did use a form of frequency hopping, later networks have employed direct sequencing and orthogonal frequency division multiplexing.

What is a FMCW radar?

A T Principle of FMCW radar M O S frequency-modulated continuous-wave A radar transmitting a continuous carrier modulated by a periodic function such as a sinusoid or sawtooth wave to provide range data (IEEE Std. 686-2008). Modulation is the keyword, since this adds the ranging capability to FMCW radars with respect to unmodulated CW radars.

What is the Doppler frequency for CW radar 11?

CW Radar 11. Doppler frequency for CW radar  fr= fo + fd … if target is coming  fr= fo – fd … if target is moving away  Let R be the distance from radar to target.  Let unit wavelength is for λ distance.  So total no. of wavelength = 2R/λ (two way path)  One wavelength corresponds to 2п radian phase.  So total phase φ= 4пR/λ

How do you calculate the Doppler frequency of a radar?
