5.The water flow rate for a particular sprinkler is 24 gpm. The water must be projected at least 20 feet in radius. The sprinkler is mounted 11 feet above the ground and is aimed at an angle of 28 degrees above the horiztonal. With what velocity must the water leave the sprinkler? What diameter (inches) should the opening be to achieve this velocity?
Water Velocity =
Diameter Opening =
6.Human blood of density 1050 kg/m3 is held a distance of 40 cm above an arm of a patient to who it is being administered. How much higher is the pressure at this position that it would be if it were held at the same level as the arm?
Pressure =
7.A farmer owns a well that is 217 feet deep. He wants to pump 820 gallons of water per minute to the surface. The pressure at the surface must be 49 psi to operate his center pivot. How much horsepower will be needed from his irrigation power unit? (Note: Power = pressure x flow rate)
Power =
