Steam enters a turbine operating at steady state with a mass flow of 10 kg/s, a specific enthalpy of 3100 kj/kg, and a velocity of 30 m/s. at the exit, the specific enthalpy is 2300 kj/kg and the velocity is 45 m/s. the elevation of the inlet is 3 m higher than at the exit. heat transfer from turbine to its surroundings occur at rate of 1.1 kj per kg of steam flowing. let g 9.81 m/s. determine the power developed by the turbine, in kw.

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
