A 1.2m3 tank is filled with water mixture at 200C if 90% of the mass is liquid and the rest is vapor what is the total mass in the tank in kg

Mr Alvin wanted to find out more about saturated liquid-vapour mixture. Hefabricated a piston-cylinder system which contains 1.5 kg of steam at 1.00 MPaand 350°C. The steam is cooled at a constant pressure until half of the masscondenses.a) Deduce the quality of vapour after the cooling process.b) Calculate the volume change for the entire process (in m3).c) Sketch the P – V diagram for this process.d) Determine the work done for this process (in kJ).e) Is it work done on or by the system and why?

A rigid tank (0.010 m³) contains saturated liquid water at 160 deg C. How much heat (kJ) must be added for the pressure to be 800 kPa and a temperature of 200 deg C?

Find the gas constant for N2 (nitrogen) in J/(kg .K)

Q/ A radiator of steam heating system has a volume of 0.2 m'. When the radiator is filled with saturated steam at a pressure of 1.5 bar all valves are closed. After a period of time the pressure inside the radiator becomes 1.4 bar due to heat lost to surrounding air. Calculate: 1- mass of steam within the radiator. 2- mass and volume of liquid water at the final state. 3- mass and volume of vapor at the final state. From steam tables, at 1.5 bar, Since all valves are closed the specific volume of steam remains constant as heat is lost. At 1.4 bar, Since v2 < v g at 1.4 bar the steam becomes wet.

A container is filled with 0.03 kg of Refrigerant R-134a at a temperature of 40 °C. What is the pressure if the volume is:a. 370 cm3b. 2260 cm3c. If any of the above conditions correspond to both liquid and vapor being present, find the quality of the mixture.

Mr Zul operates a hot plate. He places a closed, rigid container of volume 0.5 m3on the hot plate. Initially, the container holds a saturated mixture with quality ofvapour of 0.5, at a pressure of 100 kPa. After heating, the pressure in the containerincreases to 150 kPa.a) Calculate the mass of vapour at the initial and final states (in kg).b) If heating is allowed to continue, find the pressure (in kPa) when thecontainer holds only saturated vapour.c) Sketch the T – v diagram for this system.
