5. Water flows from the bottom of a large tank where the pressure is 120 psia to a turbine, located 65 ft. below the bottom of the tank that produces 40 hp. The pressure at the turbine exit is 42 psia and the water velocity is 36 ft/sec. The flow rate of the water is 127 lbm/sec. If the friction loss in the system, not including the turbine, is 32 ft lbf/lbm, what is the efficiency of the turbine

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
