A piston-cylinder assembly contains ammonia, initially at a temperature of -20°C and a quality of 60%. The ammonia is slowly heatedto a final state where the pressure is 6 bar and the temperature is 140°C. While the ammonia is heated, its pressure varies linearlywith specific volume.For the ammonia, determine the work and heat transfer, each in kJ/kg.

To solve this problem, we can use the first law of thermodynamics, which states:ΔU=Q−W Where:ΔU is…

A steam turbine is to operate on a simple regenerative cycle. Steam is supplied dry saturated at 40 bar, and is exhausted to a condenser at 0.07 bar. The condensate is pumped to a pressure of 3.5 bar at which it is mixed with bleed steam from the turbine at 3.5 bar. The resulting water which is at saturation temperature is then pumped to the boiler. For the ideal cycle sketch the process on the T-s diagram and calculate, neglecting feed pump work,The amount of bleed steam required per kg of supply steamThe thermal efficiency of the plantThe specific steam consumption

Two spherical vessels of different sizes contain the same gas and are connected by means of a pipe with a valve. Sphere A has a diameter of 5 foot at the given pressure gauge of 50 kgf/cm2. Sphere B contains the same gas at 20 kgf/cm² gauge. The valve is opened and when the properties have been determined, it is found out that the gauge pressure is 36 kgf/cm2. The temperature at the two vessels before and after opening the valve is maintained at 21.1°C. If the barometric pressure is 750 torr and the gas inside the sphere is oxygen, find the following: The volume of sphere A is 113097.33 in3 The pressure of sphere A is 711.43 psia The temperature of sphere A is 529.98 R The pressure at sphere B in psia Temperature at sphere B in F The pressure of the gas when mixed in psia The temperature of the gas when mixed in K The atmospheric pressure in psi The diameter of Sphere B The total mass of the gas after opening the valve
