3. The design of a pump and pipe system has been completed, except for the valves. The systemis used to transpor10t water at 120°F through 2 nom sch 40 commercial steel pipe at a requiredflow rate of 85 gpm. Without the valves, the pump selected has the capability to overcome anadditional 18 psi of pressure drop due to the valves and still provide the required flow rate. Thepipe/valve joints are threaded. Determine how many 2-inch globe valves can be installed in thispump and pipe system.

The system shown below uses a pump to transfer heavy fuel oil (T= 25°C) from the lower tank to the upper tank at the rate of 3600 L/min. All pipe is DN 100 Schedule 40 steel (total system length of 310 m) and the pressure line has two 90° long radius elbows and two 45º standard elbows. Valves are: fully open gate valve(s); 2 swing-type check valve, fully open butterfly valve. Determine: a. The head loss in meters due to pipe friction. b. The head loss in meters due to minor losses c. The required pump power in kW. d. The pressure at the pump inlet (suction line is 10 m long). Is this pressure a vacuum? e. The pressure at the pump outlet.
4. A special oil is to be used in an absorption tower. The preliminary design of the unit requires the oil to be pumped from an open tank with a 10 ft liquid level above the floor and forced through 150 ft of 3 inches schedule 40 pipe with a ball check valve and 5 elbows into the top of a tower 30 ft above the floor. The operating pressure in the tower is to be 52 psig and the oil requirement is estimated at 50 gpm. The viscosity of the oil 15 cP and its density is 53.5 Ibm/ft. Assuming the pumping outfit operates with an overall efficiency of 60%, what horsepower input will be required for the pump motor?
How to work out a Bernoulli pipe diameter change to increase or decrease flow into a Ram pump drive pipe. The ram pump selected is a: RAM PO400 with a 80mm drive pipe, will deliver 19200 liters per day to 125m The elevation of ram pump is 334m The elevation of drive inlet pipe is 359m The height being pumped to is 111m
Problem 2. Water at 150°F is pumped at the rate of 60 gal/min from a reservoir at atmospheric pressure. The gauge pressure at the end of the discharge line is 42 psi. The discharge point is 12 ft above the level is the reservoir and the suction line is 6 ft above the level of the reservoir. The discharge line is a 1 ½ in. nominal dimeter steel pipe with a schedule number of 80. The pressure drop due to friction in the suction line is known to be 0.8 psi, and that in the discharge line is 7.2 psi. The mechanical efficiency of the pump is 70%. Calculate (a) the developed head of the pump and (b) the total power input. (c) If the pump manufacturer specifies a required NPSH of 8 ft, will the pump be suitable for this service?

Problem # 3: Friction losses and volumetric discharge through a water piping system The cold-water faucet in a house is fed from a main water line through the following simplified piping system: A. A 160 ft long ¾ in ID copper pipe leading from the main line to the faucet base B. Six 90° standard elbows C. One wide-open angle valve with no obstruction D. The faucet which is considered to be composed of twd parts: 1) a half-open globe valve and 2) a nozzle having a diameter of 0.10 in. The pressure in the main line is 60 psig (virtually independent of flow) and the velocity there is negligible. At the faucet, the pressure is atmospheric. Assume the density of water to be 62.4 lbm/ft and the kinematic viscosity of water is 1.22 ×10³ ft²/s. Find the maximum volumetric flow rate of discharge from the faucet. This is trial and error problem. For a first trial, assume the Fanning friction factor to be 0.007. Use 5×106 ft for copper roughness. Neglect changes in elevation throughout the…

Water at 40°F is flowing downward through the fabri- cated reducer shown in Fig. 7.11. At point A the velocity is 10 ft/s and the pressure is 60 psig. The energy loss be tween points A and B is 25 lb-ft/lb. Calculate the pressure at point B.
A piping system is to be installed at place where the pump will transfer the fluid from tank A to tank B. There are two suggested piping designs available to carry the fluid efficiently. Compute and determine which of the available piping arrangement will experience the less pumping powerwith given flow conditions. Discuss the results. Flow conditions are same for both type of designs and given as: Pipe material: stainless steel Volume flow rate: 40 L/sec Assume the working fluid is water at standard atmosphere temperature and both tanks areopen to atmosphere. Pipe inlet is sharp-edged and bends are sharped without vanes. Elevations are as ?? = ?? ? and ?? = ?? ?
Calculate the power supplied to the pump shown if its efficiency is 75%. Water is at 25 degrees Celsius is flowing at the rate of 50.0 m3/h. The suction linf is a standard DN 100 Schedule 40 steel pip, 15m long. The total length of DN 50 Schedule 40 steel pipe in the discharge line is 200m. The elbows are tight, the entrance to the pipe is flush and the globe valve is completely open. Draw the line of total and piezometric heights.
