Steam enters a turbine with a pressure of 3.0 MPa and temperature of 400°C. Saturated vapor at 100°C leaves the turbine. At steady state, the turbine develops work in the amount of 540 kJ/kg of steam flowing through the turbine. Ignore the heat loss from the turbine to its surroundings. Determine the rate of heat transfer per kg of steam flowing. a. - 17.8 kJ/kg b. - 14.8 kJ/kg c. - 20.8 kJ/kg d. - 1094.8 kJ/kg

What precautions should you take to prevent injuries when dealing with heavy loads?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

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
