- Determine the power requirement of the pump shown in Figure 3.0, assuming it has an efficiency of 88%. The system has a loss coefficient of 3.0 up to point A, and K =1.2 from point B to point C. Neglect any losses through the exit nozzle. Additionally, compute the pressures at points A and B. Water 15 m 2 cm 4 cm dia. 5 cm dia. Figure 3.0 400 kPaarrow_forwardA horizontal 150 mm diameter pipe gradually reduces its section to 50 mm diameter, subsequently enlarging into 150 mm section. The pressure in the 150-mm pipe at a point just before entering the reducing section is 140 kPa and in the 50 mm section at the end of the reducer, the pressure is 70 kPa. If 600 mm of head is lost between the points where the pressures are known, compute the rate of flow of water through the pipe.arrow_forwardpump is used to collect water from an underground tank. the tank water level is 5.44 meters below the pump and the flow is 25.5 litres per second through a 75 mm diameter pipe. calculate the pressure pump and the inletarrow_forward
- Gasoline at 77°F flows from a pressurized upper tank to a vented lower tank as shown in the figure below. A length of 1-inch Schedule 40 pipe connects the two tanks a Calculate the air pressure (in psi) above the gasoline in the upper tank that will result in a flow rate of 35 gpm into the lower tank for the dimensions shown The head loss due to pipe friction is 52.8 feet and you DO NOT need to calculate this! As the upper tank drains does the air pressure in the upper tank need to be neld constant to maintain the flow rate at 35 gpm? Briefly explain your answer. C The pressurized upper tank is converted to an atmospheric tank and a pump is installed in the system. If flow rate and pipe friction remain the same, how much horsepower does the pump put into the system?arrow_forwardShow complete solution and formulas used. Show the schematic diagram too. Calculate the required pipe diameter to avoid cavitation, if the pump delivers Q = 30US gallon/min water from a closed tank, where the pressure (above the water level) is p = 40kPa. The equivalent length of the smoothened concrete pipe on the suction side is 12m while the suction flange of the pump is 8m below the water level. The vapour pressure at the given water temperature is 2.8kPa. The required net positive suction head is NPSHr = 3.2m.arrow_forwardPlease solve this in quickly please please pleasearrow_forward
- 2. An inclined venturi tube containing water has an inlet of 300 mm diameter and a throat of 150 mm diameter. The difference in head between the inlet and the throat is 250 mm. Neglecting losses, calculate the discharge through the venturi meter.

The installation of pipe system is as shown in the figure below. Considering the mass flow of the water supplied to the pipe is 5,1 kg/s and the surface roughness of the pipe is equal to the 5 micron, please compute the total pressure loss of the system in Pascal.arrow_forwardSaturated water at 310K is being pumped from a tank to an elevated tank at the rate of 7L/s. All of the piping is in 5-in. schedule 40 steel pipe. If the 2 fittings used is 90° ell standard long radius, The pump has an efficiency of 80%. Calculate the kW power needed for the pump.
