rigid tank

The rigid tank illustrated in fig P4-124 has a volume of 0.06m^3 and initially contains a two-phase liquid -vapor mixture of H2O at a pressure of 15 bar and a qualityof 20%. As the tank contents are heated, a pressure-regulating valve keeps the pressure constant in the tank by allowing saturated vapor to escape. Neglecting kineticand potential energy effects:
(a) Determine the total mass in the tank, in kg, and the amount of the heat transfer, in KJ, if the heating continues until the final quality is x=0.5

Answer #1

solved a similar question already with different numbers.. i put the question and the answer.. hope it helps!! :) kindly rate a life saver :)

A rigid tank has a volume of 0.06m3and initially contains a two-phase liquid-vapor mixture of water at p = 1500 kPa and a quality x =20%. As the tank contents are heated, a pressure-regulating valve keeps the pressure constant in the tank by allowing saturated vapor to escape. Whenno liquid remains, the valve is closed the tank is heated to T2= 350oC. Neglect kinetic and potential energy effects.

Determine the total heat transfer if the systemusing the first law of thermodynamicsand draw and label the P-v diagram.

    A rigid tank having a volume of 0.1 m3 initially contains water as a two-phase liquid-vapor mixture at 1 bar and a quality of 1%. The water is heated in two stages: Stage 1: Constant-volume heating until the pressure is 20 bar. (treat as closed system) Stage 2: Continued heating while saturated water vapor is slowly withdrawn from the tank at a constant pressure of 20 bar. (Note: Use transient analysis with all the water leaving having a quality of...

    i want the solution with explaination in a good handwriten .. A rigid, insulated tank fitted with a paddle wheel is filled with water, initially a two-phase liquid-vapor mixture at 200 kPa, consisting of 0.04 kg of saturated liquid and 0.04 kg of saturated vapor. The tank contents are stirred by the paddle wheel until all of the water is saturated vapor at a pressure greater than 138 kPa. Kinetic and potential energy effects are negligible. For the water, determine...

    A rigid tank, whose volume is 0.5 m3, initially containing ammonia at 20oC, 1.5 bar, is connected by a valve to a large supply line carrying ammonia at 12 bar, 60oC. The valve is opened only long enough to fill the tank with additional ammonia, bringing the total mass of ammonia in the tank to 143.36 kg. Finally, the tank holds a two-phase liquid-vapor mixture at 20oC. Ignoring kinetic and potential energy effects, determine the heat transfer between the tank...
