A pump is used to transfer crude oil from a non-pressurized oil tanker to a storage tank at a petrochemical refinery, both containing free surfaces open to the atmosphere during the transfer. The effective length of the pipe, including fittings, used to transfer the oil is 2,000 ft. The discharge at the storage tank is 40 ft. above the pump outlet and the pump is level with the oil tanker's liquid free surface. If the required flowrate during the transfer is 75 gpm and the pressure measured at the outlet of the pump is 120 psig, what pipe diameter is needed for this process? Oil properties: p-53 lb/ft3, μ-13 cP

What is the minimum power required from the pump to deliver the oil from Reservoir A to Reservoir B as shown in Figure 2 at a rate of 0.30m³/s? The pump has a 70% efficiency rating.

Water at 15°C is pumped from a reservior at a rate of 0.2428 m³/s where the local atmospheric pressure is 96.5 kPa. The total head loss in the suction pipe is 1.1 m. From the manufacturer data, the NPSH required at this operating point is 6.6. Determine the maximum height hs (meters) before cavitation can occur. Round off your answer to 3 decimal places.

Water at 15°C is transported from a large open tank to the bottom of another open tank above. The surfaces of the two tanks are kept at 160 ft apart vertically. The pipes used have an ID of 3.5 inches, and a total length of the pipe used is 150 ft. In the system, there are two fully open gate valves, 6 90° elbows, and 2 standard tees. The pump used has a mechanical efficiency of 60%, and the volumetric flow rate of water is at 35 (ft^3)/s. Frictional losses due to sudden contraction and expansion are negligible. Determine the Reynolds number of the flow
4. Water (p = 1000 kg/m³) is transferred from a large lake to an open storage tank located at elevation as shown in the Figure 2 below at a flowrate of 90m³/hr. The losses through pipe and fittings (hL) is given as 8m. Determine the mechanical efficiency of the pump if the shaft power required is 12kW. State the assumptions made in your calculations. 30 m WaterLevel Pump Centre Figure 2 Tank
On a trip to the beach (Patm 1 atm or 101.3 kPa), a car runs out of gasoline and it is necessary to siphon gasoline from a Good Samaritan's car. The siphon is a hose with a small diameter and to start the action it is necessary to insert one end into the tank full of gasoline, fill the hose with it through suction and then put the other end in a can that is placed under the tank level. The difference in pressure between point 1 (on the free surface of the gasoline in the tank) and point 2 (at the outlet of the tube) causes the liquid to flow from the highest elevation to the lowest. In this case, point 2 is located 0.75 m below point 1, and point 3 is 2 m above 1. The siphon diameter is 4 mm and friction losses in it must be ruled out. Determine: a) theminimum time to bring 4 L of gasoline from the tank to the can and b) the pressure at point 3. The density of the gasoline is 750 kg / m3.
Problem 5. A horizontal rough pipe with surface roughness of 1.5 × 104 m is used to transport pressurized air at a flow rate of 7 × 102 m³/s. The design guidance requires that the pressure drop must be no more than 4.2 kPa per 50 m length of the pipe. Determine the minimum diameter of the pipe
Question 1 A pipeline of length 2000 m and diameter 200 mm connects two water supply reservoirs together. (a) If the value of the frictional factor, f, for the pipeline is 0.02 then determine the flow in the pipeline when the head difference between the two reservoirs is 20 m. (b) If an increase in demand requires that the flow be increased by 40% then determine what length of the same diameter pipe is required to satisfy this demand if it is connected as shown in Figure 1. Assume that the friction factor for the new pipe is the same as the existing one. New pipeline 20 m
There is a storage tank with a height of 5 m. Initially the tank is empty. The cross- sectional area of the tank is 1m?. There is a hole in the storage tank at a level of 2m from the bottom of the tank. The relationship between the volumetric flowrate through the hole and the level of the tank is q=vh. In addition there are two valves at the top and bottom of the tank for inlet and outlet streams. Suddenly, the two valves at the top and bottom of the tank are opened where inlet and outlet stream volumetric flowrates became 1m/s and 0.2m2/s. a)Determine the time for the liquid level to reach 2m
oil is being pumped from an open tank A(elev = 110) to another open tank B (elev = 220m) with a total head loss of 15m of oil. The pump has a power rating of 210kW and an efficiency of 65%. Pipe 1 (D=200mm) connects Tank A and the pump while Pipe 2 (D=150mm) connects the pump and tank B. Calculate the velocity of flow in pipe 1, volumetric flowrate of oil, flowrate of pipe 2 and power output of the pump.
As shown in figure below, oil can be siphoned from a tank using a flexible hose, provided that the end of the hose at Point B, is below the free surface in the tank at Point A. The maximum elevation of the hose is at Point C. Oil is being siphoned from the tank through a constant-diameter hose. The end of the siphon at Point B is 6.71 meters below the oil top surface level of the tank at Point A. If the gauge pressure at Point C is 90.257 KPa and the density of oil is 890 fraction numerator k g over denominator m cubed end fraction , the vertical distance between Point C and Point B in meters is
QUESTION 2 Discharge occurs through a vertical pipe of a single-acting piston pump that is 2 m in length, 50 mm in diameter, and is fitted with an air chamber. The piston has a diameter of 150 mm and a stroke length of 300 mm. The pump is 1.9 m above the water level in the sump. Assume the atmospheric pressure to be 10.3 m of water, Fanning friction factor of 0.007, and the speed of the pump is 50 rpm. Determine the flow rate into or out of the air chamber when the crank makes an angle of 10°, 110°, and 170° with the inner dead center.
