2 A horizontal garden hose 15 m long with an interior diameter of 1.25 cm is used to deliver water at the rate of 40 cm'/s. What is the pressure drop from one end of the hose to the other? (Hint: Assume a tem- perature of 20°C.)

A 0.025 m diameter pipe carries oil of sp. gr. 0.9 at a velocity of 3 m/s. At another section the diameter is 0.020 m. Find the velocity at this section?

m². -5 S Figure shows a portion of a fire protection system in which a pump draws water at 60°F (v =1.21 ×10¯ from a reservoir and delivers it to a point B at the flow rate of 1500 gal/min.

A centrifugal pump having a head-capacityrelationship given by the equation ha=180 –6.10 X 10-4 Q2, with ha in feet when Q is ingpm, is to be used with the system shownin the figure, For Z2-Z1= 50 ft, what is theexpected flowrate if the total length ofconstant diameter pipe is 600 ft and thefluid is water? Assume the pipe diameter tobe 4 inch and the friction factor to be equalto 0.02. Neglect all minor losses.
