A *** hydrant delivers water of density ρ* at a volume rate L. The water travels vertically upward through the hydrant and then does 90 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:
(A) ρVL
(B) zero
(C) 2ρVL
(D) √2ρVL
