a rigid 14 l vessel initially contains refrigerant 134a at 30 c and has a specific volume of 0.07m^3/kg. the mixture is having heat transfer to reach a pressure of 200kPa. calculate the heat transfer required for this process. state the process is heat addition or rejection to or from the system.
with clear steps please Problem #6 A rigid tank contains initially saturated water mixture at 205 °C with a quality of 50%. Heat is added until the final temperature is 250 °C. Describe the phase at the final state and draw the process on a T-v diagram.
A rigid tank with a total volume of 0.8m3 initially contains water in the form of a saturated liquid-vapour mixture at P1=500kPa. The liquid portion of the mixture initially occupies a volume of only 0.5L (the remainder is vapour). Steam from a supply line at Pi=1000kPa and Ti=500°C is then injected into the tank until the pressure in the tank reaches P2=800kPa. At this point (final state), the mass in the tank is m2=2.8kg. a) Find the initial quality x1...
Problem 3 A rigid 6L-tank contains 3.3 kg of water initially at 30°C. The tank is heated to 175°C by a heat pump that receives heat from surroundings transfer to the water, (b) the change in entropy at 25°C. The process is reversible. Find (a) the heat Problem 3 A rigid 6L-tank contains 3.3 kg of water initially at 30°C. The tank is heated to 175°C by a heat pump that receives heat from surroundings transfer to the water, (b)...
it is 100 3. A rigid tank initially contains 0.32 kg steam at 4 MPa, superheated by 350°C. Now the steam loses heat to the surroundings and the cooling of tank continues until the cylinder contains water at x°C. Determine; (x is the percentage of each student's number based on the last digit. For example, for 20171061 it is 100 °C. If your number is greater than 3, multiply by 10.) (a) the final pressure and the quality (if mixture),...
A rigid tank contains a two-phase mixture of water and steam at a quality of 0.65 and a pressure of 20 psia. The mass of the mixture is 0.26 lbm. The mixture is heated until the final quality is 0.95. Compute the final pressure and the heat added. Please show formulas. This will help tremendously.
Water, initially saturated vapor at 2 bar, fills a closed, rigid container. The water is heated until its temperature is 400°C. For the water, determine the heat transfer, in kJ per kg of water.
A rigid tank initially contains 0.32 kg steam at 4 MPa, superheated by 350°C. Now the steam loses heat to the surroundings and the cooling of tank continues until the cylinder contains water at 90°C. Determine; (a) the final pressure and the quality (if mixture), (b) the boundary work, (c) the amount of heat transfer (d) and the total entropy generation if the Tsur=20 °C.
