As seen in Figure 3 below, the water from the tank 1 is pumped to the tank 2 with a flow rate of 5,664 liters/s, passing through a pipe with a diameter of 50.8 mm and a length of 121.92 m. Some of the local losses in the system are also shown on the figure. Calculate the effective power of the pump by taking the relative roughness ɛ / d = 0.001 Note: For all questions, pwater = 1000 kg/m³, g=9.81m/s^2 , the kinematic viscosity of water is 1.0219x106 m²/s and the questions can be solved by accepting the values that are not given.
A pipe has an initial radius of r1, which then changes to a radius of r2. The velocity of the water in the initial part of the pipe is v1. The segment of the pipe with the smaller radius is also 0.5 m higher than the initial pipe segment. What is the pressure difference between the two parts of the pipe? let r1=10cm let r2=6cm let v1=5m/s b) What is the volume flow rate in the pipe?
Oil of specific gravity 0.750 is pumped from a tank over a hill through a 24′′ pipe with the pressure at the top of the hill maintained at 25.5 psi. The summit is 250 ft above the surface of the oil in the tank, and oil is pumped at the rate of 22.0 cfs. If the lost head from tank to summit is 15.7 ft, what horsepower must the pump supply to the liquid? Indicate the Free Body Diagram
A pump delivers water, density =1000kg/m3, at a volume flow rate of 0.004256 m3/sec. If the head developed by the pump is 4.01 m, determine the fluid power in Watts. Take g=9.81 m/s2. State the answer to two decimal places.
A vessel is being filled with water through an inlet at section 1 having a diameter of 40 mm and a faucet at section 3. The velocity at section 1 is given as 5 m/s, while the discharge at section 3 is given as 0.012 m^3/ s. Assume constant water level. Use 60 mm for the diameter of the outlet at section 2. A. What is the discharge at section 2? B. What is exit velocity at section 2? C. If the water level varies and the velocity at section 2 is 8m/s find the rate of change when d is equal to 1000mm?
Gasoline at 38°C is being drawn from a closed tank having a pressure of 70kPag. The level of gasoline in the tank is 2.5m above the pump centerline. The suction line friction loss is 0.6m. The vapor pressure of the gasoline is 48kPa absolute and its specific gravity is 0.72. Determine the NPSH available.
A pump is designed to fill a pressurized tank rated at 1 MPa anda height of 23 m. Determine the power requirement of the pump inkW if the flowrate is measured at 20 m3/min.
Reservoir A (Elevation 300m) supplies water to reservoir B (Elevation 180m) thru a 450 mm ductile iron pipe. A turbine is installed in the same level with Reservoir B. The total system flow is 350 gpm determine the the output power in Hp if the turbine is 75% efficient and the total headloss of the system is 3.5m.
The task is to to transfer the fluid from the source towards the tank (TANK A) lying on an elevated platform as shown. The goal is to fill up that 16.49 m by 2.23 m by 6.36 m tank (TANK A) within 11.5 mins (from empty to full). Your budget is limited to 605,000 pesos. Head loss on pipe due to friction is 1.23 meters per 1 meter of pipe. Because it's Fluid Machinery and not Engineering Economics, it's ok for your design to exceed the budget BUT YOU HAVE TO JUSTIFY IT.
