1.A fireman reduces the exit area on a nozzle so that the velocity inside the hose is quite small relative to the exiting velocity. What is the maximum exiting velocity and what is the maximum height the water can reach if the pressure inside the hose is 200 psi?
2.The dimensionless henry's constant for TCE at 25 degrees celsius is 0.4. A sealed glass vial is prepared that has an air volum of 4mL overlying an aquesous volume of 36mL. TCE is added to the aqueous phase so that initally it has an aqueous phase concentration of 100 ppb. After the system equilibrates, what will be the concentration of TCE in the aqueous phase?
