1. A jet engine receives a flow of 150 m/s air at 75 kPa, 5?C, across an area of 0.6 m2 with an exit flow at 450 m/s, 75 kPa, 800 K. Find the mass flow rate and thrust
2. How large a force must be applied to a squirt gun to have 0.1 kg/s water flow out at 20 m/s? What pressure inside the chamber is needed?
