steam at 5 pma and 650 c enters adiabatic turbine at a velocity of 80 m/s. Following its expansion in the turvine, it exits at 50kpa 150c and a velocity of 140 m/s. thje power output of the turbine is 8 MW calculate the mass flow rate of the steam determine the state of the working fluid at the outlet of the turbine of the expansion was isentropic

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.

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.
