Question
A fire hydrant (as shown in the figure) delivers water of density r at a volume rate L. The water travels vertically upward through the hydrant and then does 900 turn to emerge horizontally at speed V. The pipe and nozzle have uniform cross-section throughout. The force exerted by the water on the corner of the hydrant is
Options
A.ρVL
B.zero
C.2 ρVL
D.√2 ρVL
= 
= √2V [ρ L] = √2 ρVLMore Fluid Mechanics Questions
