The unit weight of water at 50°F is 62.4 pcf. If the volume of the vessel that contains water is 3.50ft³. A. What will the be the change volume when it is heated to 160°F ( unit weight of water is 61 pcf 160°F) B. Compute the percentage change of volume C. What weight of water must be removed to maintain the original volume (Our Subject is FLUID MECHANIC)

Given A pipe is tapered to form a nozzle as shown in the figure, and the nozzle produces a jet velocity of 102 ft/s. 1.0-in diameter Flow 0.75-in diameter Required Calculate the required pressure in the larger section to produce the jet velocity given, in psi to the nearest 10th. The fluid is water at 180°F (Appendix A). Your Answer:

Which of the following unit is NOT the Pressure unit? o Pascal o psi o kelvin o standard atmosphere • A vacuum gage connected to a chamber reads 7 psi at a location where the atmospheric pressure is 14.5 psi. What is the absolute pressure in the chamber? o 7.5 psi o 21.5 psi o -7.5 psi o 8.7 psi Pressure is a scalar quantity, the pressure at a point in a fluid is the same in all directions. o True o False
