a pump draws water from a pit through a vertical 30 cm pipe which extends below the water surface. it discharges into a 15 cm horizontal pipe 4.0 m above the water surface. while pumping 60 liters/s, a pressure gage on the discharge pipe reads 165 kpa and a gage on the suction pipe shows a vacuum of 35 kpa. both gages are close to the pump and are separated by a vertical distance of 90 cm. compute the head lost in the suction pipe. compute the change in energy per second between the gages. what is the power output of the pump?

A 2-inch diameter hose is conveying water at a flow rate of 20 gpm from point A to point B. The pressure at point A is 40 psi. The elevation at point A is 20 ft above mean sea level (MSL) and the elevation at point B is 18.5 ft above MSL. The hose is 100 ft long. Determine (a) pressure at point B if there is no head loss, (b) pressure at point B if head loss is 1 inch per foot of pipe length. (c) Compare pressure at B with and without headloss - what impact does head loss have?

Q1: A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a distribution system for potable water. A completely filled and pressurized water tank was found with a small leakage (a hole 5cm in diameter) located on the sidewall of the tank, around 5 meters below the top of the tank. Please calculate the velocity of leakage water that discharges to the normal atmosphere. The dimension of the tank is 20-meter in height and 10-meter in diameter. The gauge pressure of the water tank top is 0.1M Pa. The Bernoulli equation is: P₁/pg + V₁²/2g +h₁ = P₂/pg + V₂²/2g +h₂ Gauge Pressure: 0.1 M Pa 5 meters Leakage velocity?

Water flows at 0.72 m/s through a pipe 17 cm in diameter when the pressure is 460,000 Pa. What is the water velocity & the pressure in the pipe if it shrinks down to 6 cm in diameter. Note: (The pipe is horizontal & ρwater = 1000 kg/m3.)
