Determine the minimum distance a pump should be located below the water surface elevation (Zs) in order to avoid cavitation. The total friction head loss (hLf) is 0.04 meters, and the sum of all minor losses is 0.2 meters. The atmospheric pressure is 101 kPa and the water vapor pressure at 20º C is 2.3388 kPa. The pump required net positive suction head (NPSHR) is 12 meters.

Waters enter a pump through a 25 cm. dia. Pipe at 35Kpa. It leaves the pump at 140 kPa through a 15 cm. dia. pipe. If the flow rate is 150 li/sec., find the horsepower delivered to the water by the pump. Assume suction & discharge sides of pump are the same elevation.
Water at 20C with a density of 0.9982 g/cc and a viscosity of 1 cP is flowing from an open reservoir throught he piping system below and assumed to be discharged at an atmospheric condition. The piping system is composed of 3 m - 3” schedule 40 pipe with a standard gate valve wide open installed and 6 m - 2” schedule 40 pipe. The reservoir has a level of water of 3.5 m. Calculate the average volumetric flow rate in liters per minute. (Use equation 6-37 of Perry’s Handbook (9th edition) to calculate for fanning friction factor).
pls answer asap for my hydraulics course. A 30 cm diameter pipe is connected by a reducer to a 10 cm diameter pipe. Points 1 (on the 30 cm diam.) and 2 (on the 10 cm diam.) are along the same elevation. The pressure at 1 is 250 kPa. The flow is 30 liters per second and the energy lost between 1 and 2 is equivalent to 20 kPa. Compute the pressure at 2 if the liquid flowing has a specific gravity of 1.50.

The pressure at the 2nd floor faucet in the residential building is estimated to be about 43 psi for Q = 2.5 cfs and D = 3.5 inch (Figure 1), which is less than the recommended domestic pressure range of 50 to 60 psi. It is considered that an additional pump will be installed at point 1 to provide the recommended pressure at the faucet. Estimate the additional pump horse-power requirement at point 1 to provide 60 psi pressure at the faucet.
