Water flows from a tank through a pipe section as shown below. Points 1 and 2 are located at the same vertical height and the pressure gauges are mounted at the same vertical position. If the water velocity at point 1 is negligible, frictional losses are essentially zero, and there are no entrance/exit effects in the tank and pipe, how is the pressure at points 1and 2 related? O P1 = P2 because friction is negligible in the flowing fluid O P1 < P2 because of the force required to push fluid into the pipe Can't determine without knowing the fluid density and viscosity O P1 > P2 because pressure decreases as velocity increases according to the Bernoulli principle
