1. (25pt) Water at room temperature is pumped through a smooth pipe. The pipe has diameter of 10cm. The total length is 10 km. The discharge is 80 m²/h. A pump is installed at the inlet. At the exit of pump, the absolute pressure of the water is 25 atm. The exit exposes to the atmosphere and its elevation is 100 m higher than the inlet. Estimate the frictional head loss hf.

4. An old, rough-surfaced, 2-m-diameter concrete pipe with a Manning coefficient of 0.025 carries water at a rate of 5.0 m'/s when it is half ful. This pipe is to be replaced by a new smooth pipe with a Manning coefficient of 0.012. Determine the diameter of the new pipe if it also is to flow half full with a flow rate of 5.0 m'/s Water initially flowing in the horizontal section of pipe of diameter 12.00 cm shown in...
In order to provide irrigation, water has to be pumped to an elevation 120 m through a 600 mm pipe where the pressure required at the higher elevation is 172 kPa. The source of the water and the discharge point are at atmospheric pressure. Irrigation requirements dictate that water must be pumped at the rate of 1m3/sec. The loss of head due to friction and other factors is estimated to be 2.4m. Elevation of the water source is 60 m....
2 Underground water is to be pumped by a 80 percent efficient 10-kW submerged pump to a pool whose free surface is X m above the underground water level (see Figure 2). The diameter of the pipe is 10 cm on the intake side and 8 cm on the discharge side. Determine (a) the maximum flow rate of water and (b) the pressure difference across the pump. Assume the elevation difference between the pump inlet and the outlet and the...
8-C) As shown below water is pumped and sprayed through a nozzle into the atmosphere at 20 m/s at an elevation 10 m above the reservoir surface. The mass flow rate is 40 kg/s and the volumetric flow rate is 0.040 m3/s. The large diameter inlet pipe total length is 50 m. The pump effidency is 65%. The longer smaller diameter pipe leaving the pump is 200 m in total length. The pipes have different diameters as indicated below. The...
Q4. In a pipe 0.3 m in diameter, 0.3 m2/s of water is pumped up a hill. On a hilltop (elevation 48 m) the line reduces to 0.2 m diameter. If the pump maintains a pressure of 690 kpa at elevation 21 m calculate the pressure in the pipe on the hilltop
Underground water is to be pumped by a 78 percent efficient 5-kW submerged pump to a pool whose free surface is 30 m above the underground water level. The diameter of the pipe is 7 cm on the intake side and 5 cm on the discharge side. Determine (a) the maximum flow rate of water and (b) the pressure difference across the pump. Assume the elevation difference between the pump inlet and the outlet and the effect of the kinetic...
