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?

The figure below shows a turbine-driven pump that provides water to a mixing chamber located dz⁢= 5 m higher than the pump, where m˙=50 kg/s. Steady-state operating data for the turbine and pump are labeled on the figure. Heat transfer from the water to its surroundings occurs at a rate of 2 kW. For the turbine, heat transfer with the surroundings and potential energy effects are negligible. Kinetic energy effects at all numbered states can be ignored. Determine:(a) the magnitude of the pump power, in kW.(b) the mass flow rate of steam, in kg/s, that flows through the turbine.

A gas cylinder with interior volume 11.6 L holds compressed air at 17.4 MPa. The cylinder is joined by a hose of negligible volume to a second cylinder that’s been pumped down to vacuum. When the valve on the full cylinder is opened, the air expands to fill the entire system, all the while maintaining a constant temperature. If the energy that becomes unavailable to do work is 171.8 kJ, what’s the volume of the second cylinder (L)?
