1.A Las Vegas casino is constructing a fountain system for a glamorous water show along the Strip. The casino's uber-wealthy owner wants water shooting 30 m into the air from the pool. The engineer has to decide on a pump to produce enough pressure to drive the fountain to that height. He has a choice of five pumps: 2. (a) Produces 500 kPa 3. (b) Produces 400 kPa 4. (c) Produces 300 kPa 5. (d) Produces 200 kPa 6. (e) Produces 100 kPa In the interest of saving money the engineer must select the smallest pump that can produce enough pressure to drive the fountain. Which one will work? The water in the fountain is going to typically be at 30 C, since Las Vegas is exceedingly warm during a good part of the year. What will the exit velocity be, if the nozzle for the fountain is 4 cm in diameter?
