A fluid is flowing through a horizontal pipe of varying cross-section, with speed v ms–1 at a point where the pressure is P pascal. At another point where pressure is P / 2 Pascal its speed is V ms–1. If the density of the fluid is kg m–3 and the flow is streamlined, then V is equal to: 1) √[(P / 2ρ) + v2] 2) √[(P / ρ) + v2] 3) √[(2P / ρ) + v2] 4) √[(P / ρ) + v]
