I’d like to ask gently about the pressure
Thread Content
There is a pump on the ground, and the pressure indicated by the pressure gauge at its outlet is 0.8 MPa. The fluid flowing in the pipes is water. There is another pressure gauge located 20 meters above the pressure gauge of the pump. I would like to ask gently: what is the pressure reading at that location? Thank you
Calculate the Bernoulli equation. Make an approximate estimate: 1 atmosphere corresponds to 10 meters of water depth, so at 20 meters the pressure is roughly 0.6
Since the density of water is approximately 1000 kilograms per cubic meter and the gravitational acceleration at the Earth’s surface is about 9.8 meters per second squared, according to the principles of hydrostatics, the pressure decreases as one goes 20 meters higher due to the increase in altitude. Change in pressure = ρgh = 1000 kg/m³ * 9.8 m/s² * 20 m = 196000 Pa = 0.196 MPa. Therefore, the pressure at a height of 20 meters above is = 0.8 MPa - 0.196 MPa = 0.604 MPa. Therefore, the pressure at 20 meters above the pressure gauge of the off-tank pump is approximately 0.604 MPa. .
0.6 MPa, with one standard atmosphere decrease every 10 meters. P1-P2=pgh
0.6 minus pipeline resistance and local resistance; 0.59 as a reference
