1. How does the operator of a pumper-tanker fire engine control water flow to all the hoses in use?

2. For air flowing through a converging-diverging channel, sketch the variation of the air pressure as air accelerates in the converging section and decelerates in the diverging section.

3. Why is it that when air at 1 atm is throttled to a pressure of 0.5 atm, its temperature at the valve exit is closely the same as at the valve inlet, yet when air at 1 atm leaks into an insulated, rigid, initially-evacuated tank until the tank pressure is 0.5 atm, the temperature of the air in the tank is greater than the air temperature outside the tank?

4. If the expansion valve of a refrigerator becomes ice encased, does the throttling process model still apply? Explain.

5. Why does evapotranspiration in a tree require so much energy?

6. What are intra-articular pain pumps?
