A pressure cooker operates by cooking food at a higher pressure and temperature than is possible at atmospheric conditions. Steam is contained in the sealed pot, with a small vent hole in the middle of the cover, allowing steam to escape. The pressure is regulated by covering the vent hole with a small weight, which is displaced slightly by the escaping steam. Atmospheric pressure is 1 bar, the vent hole area is 7mm2, and the pressure inside should be 2.75 bar. What is the mass in kg of the small weight?

Steam generators are a type of heat exchanges that are used inpower plants to generate steam at desired pressure andtemperature (Fig. Q1.b). In a steam generator, saturated liquidwater at 30°C enters a 60-mm diameter tube at the volume flowrate of 12 L/s. After exchanging heat with hot gas, the waterchanges to steam and leaves the generator at a pressure of 9 MPaand a temperature of 400°C. During this process, the diameter ofthe water/steam tube does not change. Where necessary, assume air as an ideal gas and consider R = 287J/(kg.K), Cp = 1005 J/(kg.K), Cv = 718 J/(kg.K). (i) Calculate the steam mass flow rate and inlet velocity of the steam? (ii) What is the exit velocity of the steam? (iii) Calculate the rate of heat transfer (in MW) required tochange the phase of liquid water to steam.
An oxygen tank has a volume of 4 cubic meters and is at 20 degrees C and 700 kPa. The valve is opened, and some oxygen is released until the pressure in the Tank drops to 500 kPa. If the temperature in the tank does not change during the process: The mass of oxygen that has been released from the tank is.... ..kg. Assume: Oxygen is an ideal gas and its ideal gas constant is 260 N.m/kg.K Where K is the degrees, Kelvin.
Refrigerant-134a is in an insulated canister with temperature 25 C. There is a partition in the canister so the refrigerant is a saturated liquid and takes up 1/100 of the volume of the canister. The rest of the volume is evacuated. When the canister is activated by squeezing (no work done activating) the partition breaks and the refrigerant fills the total volume. Final pressure is 100 kPa. a.) What are two assumptions needed for the problem? What properties are needed to solve part b.) and c.) b.) What is the change in specific enthalpy within the canister? c.) What is the final quality of the refrigerant within the canister?

A weighted piston (total masa of 17 kg)., resting on stops in a cylnder (radius of 0.05 m) divides a container into two regions. 0.075 kg of saturated liquid water at 50 Cis contained beneath the piston. The rest of the cylinder and container is evacuated. Heat is applied to the water until the piston is lifted off of the stops and moved a distance () of 0.6 m. As the piston reaches the mouth of the cylinder, the hermetic seal is broken and the cylinder contents can now expand to fil the remainder of the evacuated space. At this instant, no additional heat is added to or removed from the system.
