Question

A closed, rigid tank is filled with water. Initially, the tank holds 1.0 lb of saturated vapor and 7.0 lb of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. Kinetic and potential energy effects can be ignored. Determine the volume of the tank, in ft3, the temperature at the final state, in °F, and the heat transfer, in Btu.

Water, initially saturated vapor at 14.6 bar, fills a closed,
rigid container. The water is heated until its temperature is
200°C. For the water, determine the heat transfer, in kJ/kg.
Kinetic and potential energy effects can be ignored.

Water of mass 2 kg in a closed, rigid tank is initially in the
form of a twophase liquid-vapor mixture. The initial temperature is
50° C. The mixture is heated until the tank contains only saturated
vapor at 110° C.
(i) Find the initial pressure, in kPa.
(ii) Find the work for the process, in kJ.
(iii) Find the heat transfer for the process, in kJ.

A rigid tank has a volume of 0.01 m3. It
initially contains saturated water at a temperature of 200
oC and a quality of 0.4. The top of the
tank contains a pressure regulating valve which maintains the vapor
at constant pressure. This system undergoes a process where it is
heated until all the liquid vaporizes. How much heat in (kJ) is
required? You may assume there is no pressure drop in the exit
line.

A 0.1-m3 rigid tank contains saturated liquid-vapor mixture of
water, initially at 150 kPa and 52 percent quality. Heat is now
transferred to the tank until the system becomes superheated vapor
and the pressure reaches 300 kPa. Determine (a) the total mass of
the mixture in the tank and (b) the amount of heat transferred.

A closed, rigid steel tank contains 1 lbm of water, initially at
260 F and a quality of 60%. The tank is fitted with a paddle wheel
and the water is stirred until the temperature is 350 F. The tank
is well insulated on the outside and the steel is in thermal
equilibrium with the water. The mass of the steel tank itself (not
including water) is 60 lbm and the specific heat of the tank is
0.115 Btu/lbm·R. Changes...

A tank having a volume of 0.85 m^3 initially contains water as a
two-phase liquid vapor mixture at 260 C and a quality of 0.7.
Saturated water vapor at 260 C is slowly withdrawn through a
pressure-regulating valve at the top of the tank as energy is
transferred by heat to maintain the pressure constant in the tank.
This continues until the tank is filled with saturated vapor at 260
C. Determine the amount of heat transfer in kJ. Neglect...

Please do it as fast as you can, with step .
1. A closed rigid tank starts with 0.017263 ft^3 of saturated
liquid and 8.3 ft^3 of saturated vapour at 200 F. The water is
heated until it contains only saturated vapour.
Please find a)original liquid mass, b) original vapor mass, c)
original quality d) final temparature and e) total heat tranfer

system, a rigid tank, contains mixture of saturated water vapor
and saturated liquid at 90 oC. Total mass is 1.5 kg. quality is
0,34. system is heated untill all liquid is converted into vapor.
how much heat is transferred to the syste, show this process in

Q3. A tank with rigid walls and a volume of
0.05 m3 initially has a two-phase liquid- vapor mixture of ammonia
at a pressure of 4 bar and a quality of 10%. The tank is then
heated such that the pressure is kept constant through a
pressure-regulating valve that allows saturated vapor to escape.
The heating continues until the quality of the mixture in the tank
is 40%. Assume kinetic and potential energy changes are
insignificant. Determine:
(i) The final...
