QUESTION 2 A 1.2-m tank is filled with water mixture at 200°C. If 90% of the...
Needh help with this
A 200-m' rigid tank is filled with saturated liquid-vapor mixture of water at 50°C. If 10% of the mass is liquid and the rest is vapor, find the total mass in the tank. If heat is added in and the mixture becomes saturated vapor, find the pressure.
In a well-insulated rigid tank which contains 2 kg of a saturated liquid-vapor mixture of water at 200 kPa, 40% of the mass is in the liquid phase. A heater is providing heat to the content of the tank so that all liquid phase converts to vapor phase. Calculate the entropy change of water in this process.
A 160 m3 rigid tank is filled with saturated liquid-vapor mixture of water at 50oC. 70% of the mass is vapor and the 30% of the mass is liquid. The mixture is then heated until its pressure is 50kPa. Determine the final temperature(oC).
A 0.3 m3 rigid tank is filled with saturated liquid water at 200°C. A valve at the bottom of the tank is opened, and liquid is withdrawn from the tank. Heat is transferred to the water such that the temperature in the tank remains constant. Determine the amount of heat that must be transferred by the time 2 of the total mass has been withdrawn. a. Hint: The phase of the water when / of the mass has exited is...
A rigid tank is filled with 260 kg of saturated liquid water at 200°C. A valve at th bottom is opened, and liquid is withdrawn from the tank. Heat is transferred to th tank such that the temperature remains constant. Determine the amount of hea the water remains a saturated liquid the entire time and that the veloc elevation change of the water leaving is negligible. (15 pts) st be transferred by the time half the mass has been withdrawn....
Don’t round any decimals please
A 160 m3 rigid tank is filled with saturated liquid-vapor mixture of water at 50 C.0.89 of the of the mixture in unit of m2/kg. Round the result to 4 decimal places.
5. Solve and submit Problem 2.A-3 by using tables. Sketch the process on a T-v diagram against the saturation lines. 2.A-3 Arigid tank with volume V 8000 cm is filled with water with quality xi 0.05 and temperature 11-140°C. a.) What is the specific volume (m/kg) and the pressure (kPa) of the water. b.) What is the total mass of water in the tank (kg)? What is the mass of liquid (kg) and the mass of vapor (kg) in the...

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 well-insulated rigid tank contains 2 kg of a saturated liquid-vapor mixture of water at 100 kPa. Initially, three-quarters of the mass is in the liquid phase. An electric resistance heater placed in the tank is now turned on and kept on until all the liquid in the tank is vaporized. Determine the entropy change of the steam during this process. Answer: 8.10 kJ/K Analysis From the steam tables (Tables A-4 through A-6)
A 2-m rigid insulated tank initially containing saturated water vapor at 1.2 MPa is connected through a valve to a supply line that carries steam at 400 °C. Now, the valve is opened, and steam is allowed to flow slowly into the tank until the pressure in the tank rises to 2.5 MPa. At this instant, the tank temperature is measured to be 350 °C. Determine a) the mass of the steam that has entered the tank from the supply...
