Steam flowing at 5.5 kg/min enters an adiabatic expander at 7.0 MPa and 650 C and leaves at 0.2MPa and 200 C. The expander delivers a total of 75 kW of power. A) Calculate the efficiency of theexpander. B) Use the temperature-independent heat capacity of water(found on inside of backcover) to assess whether steam is behaving ideally in this adiabatic expansion.

On a average work day more than work place firs are reorted

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
