Steam enters a nozzle operating at steady state at 20 bar, 253°C, with a velocity of 42 m/s. The exit pressure and temperature are 5 bar and 192°C, respectively. The mass flow rate is 3.3 kg/s. Neglecting heat transfer and potential energy, determine the inlet area in cm2.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?
