Steam is leaving a 4-l pressure cooker whose operating pressure is 150 kpa. it is observed that the amount of liquid in the cooker has decreased by 0.6 l in 40 min after the steady operating conditions are established, and the cross-sectional area of the exit opening is 8 mm2. saturation conditions exist within the cooker at all times so that steam leaves the cooker as a saturated vapor at the cooker pressure. determine (a) the mass flow rate of the steam and the exit velocity, (b) the flow energies (pv) of the steam per unit mass, and (c) the rate at which energy leaves the cooker by steam. ignore the potential energy.

Aspecial electronic sensor is embedded in the seat of a car that takes riders around a circular loop-the-loop ride at an amusement park. the sensor measures the magnitude of the normal force that the seat exerts on a rider. the loop-the-loop ride is in the vertical plane and its radius is 23 m. sitting on the seat before the ride starts, a rider is level and stationary, and the electronic sensor reads 740 n. at the top of the loop, the rider is upside down and moving, and the sensor reads 370 n. what is the speed of the rider at the top of the loop?
