Queslion 1 A piston-cylinder assembly with a frictionless piston has a volume of 0.1 m' and initially filled with steam of 0.5 kg at a pressure of 0.4 MPa. There is heat transfer until the temperature reaches 573 K. Find the total heat transfer as well as the work done during the process. Sketch the process on a P-v diagram with respect to the vapour dome.

Container is filled with water. The total volume is 5 m^3. 1% of the volume is saturated liquid and 99% of the volume is saturated steam where the pressure is 0.1 MPa within the container. Heat is transported to the container until all the water turns into saturated steam. Find how much heat isrequired for the process to occur.

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.

QI) A constant pressure piston cylinder contains 0.2 kg water as saturated vapor at 400 kPa. It is now cooled so the water occupies half the original volume. Find the work in the process. (-18.5 kJI

Determine the type of steam, given: Pressure: 770 kPa Specific volume: 260 x10-3 m3/kg O Saturated Liquid Saturated vapor O Wet Vapor O superheated Vapor

Switching the temperature for the steam table  (c)  to be 160 C and the pressure to be 5000kpa (it was a error)

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.
