1. A fire hose nozzle has an orifice diameter of 1inch. According to some fire codes, the nozzle must be capable of delivering at least 300gal/min If the nozzle is attached to a 3-inch diameter hose, what pressure must be maintained just upstream of the nozzle to deliver this flow rate?

2. Kerosene having a specific weight of 50.0 lb/ft3 is flowing at 10 gallons per minute from a standard 1-inch Schedule 40 steel pipe to a standard 2-inch Schedule 40 steel pipe. Calculate the difference in pressure in the two pipes.

3. A 4-inch diameter pipe carries 300 gal/min of water at a pressure of 60 psi. Determine:

a) The pressure head in feet of water

b) The velocity head

c) The total head with reference to a datum plane 20 ft below the pipe.

4. 8. Oil with a specific gravity of 0.90 is flowing downward through the venturi meter. If the pressure difference on the gauges is 2 psi , the diameters or 2" and 1", and the elevation difference from station 1 - 2 is 1 foot, calculate the volume flow rate of oil.
