Water is pumped from the tank 1 to tank 2 as shown below. The suction side pipe is nominal 5, schedule 40, 24 ft long, f = 0.018, and the discharge pipe is nominal 4, schedule 40, f = 0.019, and is 400 ft long. The entrance is square edged, and the elbows are 90o. There is a fully opened gate valve on the suction side and the discharge side, and there is a swing type check valve on the discharge side. Determine the system curve for the pump system.
Consider friction loss in teh 225-ft-long discharge pipe, but neglect other losses. Then, redesign the system by using a larger pipe size to reduce the energy loss and reduce power required to no more than 5.0 hp.
A hot-rolled 7-mm-diameter steel rod is axially loaded at room Temp under a fully reversed cyclic loading. under the rotating beam test, the endurance limit for this steel is 470 MPA, under static loading the ultimate strenght is 1200 MPA.
A finished 2 x 4 timber (actual size 1 5/8 in. x 3 1/2 in. x 10 ft long) is used as a fixed-end, fixed-end column. If the modulus of elasticity for the timber is 1600 ksi and a factor of safety of 3 with respect to failure by buckling is specified
An electric resistance heater now heats the water. Calculate the amount of heat added to the water and the associated change in entropy when the volume of the water is 50 times its initial value.
