5.81 a quantity of water within a piston–cylinder assembly executes a carnot power cycle. during isothermal expansion, the water is heated from saturated liquid at 50 bar until it is a saturated vapor. the vapor then expands adiabatically to a pressure of 5 bar while doing 364.31 kj/kg of work. (a) sketch the cycle on p–y coordinates. (b) evaluate the heat transfer per unit mass and work per unit mass for each process, in kj/kg. (c) evaluate the thermal efficiency.

Fluids at rest possess no flow energy. 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

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
