3. A fountain consists of a pool of water, an inlet pipe under the water that is connected to a pump and a vertical discharge pipe that discharges water from the pump in a jet. The diameter of the discharge pipe is 4.00 cm. The water rises to a height of 15.0 mabove the surface of the pool and then falls back to the pool. Friction can be neglected. Find the flow rate of water through the pump.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.
