Fluid power system Do all of your work on these sheets, if extra room is required, use extra sheets of paper and attach them to the back of the test. Label your work clearly, define the answer with the proper units, and draw a box around your final answer. Be sure that all of your work is stapled together when you hand in your test. I. For the following circuit; if: The pressure drop from point A to B is...
fluid is flowing horizontally from point 1 to point 2 as shown below. if the pressure at point 1 is 20 psi, find the pressure at point 2 in psi, if the velocity at point 1 is 11 ft/s and the velocity at point 2 is 41 ft/s. the specific gravity of the oil is 0.9. there is no energy loss or added in the system
4. The discharge pressure gauge reading is 5 lb/in2 (psi) for the pumping system shown in the sketch below, with the outlet nozzle discharging a 2-inch diameter stream of water directly to the atmosphere. The gauge pressure at the pump suction inlet at the point of incipient cavitation is (-2,071.12) lb/ft, i.e., for vapor pressure of water at 68° F of 50.54 lb/ft2 absolute, and standard atmospheric pressure 30 in Hg. Friction losses in the suction piping from the reservoir...

The system below shows a simplified schematic of an oil transfer system between tanks, from left to right: L L The oil specific gravity is 0.77 and its viscosity is 2.7 [cP). The pipes are horizontal and coaxial (neglect difference in height between suction and discharge). The tanks are closed but vented so that they are at atmospheric pressure ([atm]). Assume for simplicity that the liquid level in each tank is 2.5 (m) above the level of the pipes (in...
The sketch shows a system used to spray polluted water into the air to increase the water's oxygen content and to cause volatile solvents in the 6. water to vaporize. The pressure at B of the nozzle must be 25 psig for proper nozzle performance. The pressure at point A (the pump inlet) is -3.5 psig. The volume flow rate is 0.5 ft3/s. The dynamic viscosity of the fluid is 4.0 x 10 Ib-s/ft?. The specific gravity of the fluid...
Chemical Engineering Fluid Mechanics 30. The purpose of a centrifugal pump is to increase the pressure of a liquid in order to move it through a piping system. The pump is driven by a motor, which must provide sufficient power to operate the pump at the desired conditions. You wish to find the pressure developed by a pump operating at a flow rate of 300 gpm with an oil having a specific gravity (SG) of 0.8 and a viscosity of...
8.11 Plot each of the quantities calculated in Problem 8.10 versus condenser pressure ranging from 0.3 lbf/in. to 14.7 lbf/in.? Maintain constant net power output. Discuss. (a) Use condenser pressure of 2.0 lbf/in? (already solved in problem 10) (b) Use condenser pressure of 14.696 lbf/in?. (Solve the problem only for these two pressures and then for your graphs, connect the two dots. Because each graph will only have two dots, instead of a curve your graphs will be straight lines.)...
1 A liquid with a specific gravity of 1.26 is being pumped from A to B through the pipeline of Fig. 55.8. At A the pipe diameter is 24 in (600 mm) and the pressure is 45 psi (300 kPa). At B the pipe diameter is 12 in (300 mm) and the pressure is 50 psi (330| kPa). Point B is 3 ft (1.0 m) lower than A. Find the flow rate if the pump puts 22 hp (16 kW)...
