A rigid tank contains 1.18 kg of R134a at-28°C. The volume of the tank is 0.12368 m. The R134a is heated until its pressure reaches 200 kPa. Determine the initial pressure and final temperature. kPa oC
A rigid tank with a volume of 0.117 m3 contains 1 kg of R134a vapor at 240 kPa. Determine the initial pressure and final temperature.
A 1-mº rigid tank contains 100 kg R-134a at a temperature of 16 °C. A valve on top of the tank is opened, and saturated vapor is allowed to escape through a throttle to a collector system at 100 kPa. During the process the temperature inside the tank remains at 16 °C by heat transfer from the 20 °C surroundings. The valve is closed when no more liquid remains inside the tank. Calculate the heat transfer to the tank and...
Question 5 5 pts A diffuser, flowing R134a, has a mass flow rate of 5.0 kg/s. At the inlet, the R134a is a saturated vapor at 20°C with a velocity of 100 m/s. The area of the diffuser at the inlet is closest to: Diffuser O 5 cm2 O 20 cm2 10 cm O 1 cm2
A rigid tank contains 9 kg of air at 140 kPa and 20°С. More air is added to the tank until the pressure and temperature rise to 250 kPa and 30°C, respectively. Determine the amount of air added to the tank. Answer: 6.54 kg
Question 18 1 pts Problems 18-20 are based on the following description An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 10 kg of an ideal gas with molar mass M-16 kg/kmol, a pressure of 330 kPa, and a temperature of 50 oC. The other part is evacuated. The partition is now removed and the gas fills the entire tank. (R. - 8.31447 kJ/kmol.K) The expansion work in kJ is closer to:...
A rigid tank contains 54.5 g of chlorine gas (Cl2) at
a temperature of 72 °C and an absolute pressure of 5.60×10^5 Pa.
The mass per mole of Cl2 is 70.9 g/mol. a) Determine the
volume of the tank. b) Later, the temperature of the tank has
dropped to 33 °C and, due to a leak, the pressure has dropped to
3.40×10^5 Pa. How many grams of chlorine gas has leaked out of the
tank? (The mass per mole of...
