Test: Dynamic of Fluid Flow - 3 - Mechanical Engineering MCQ

The equation of motion for a viscous fluid known as

The rate of flow through venturimeter varies as

A smooth pipe of diameter 200 mm carries water. The pressure in the pipe at section S1 (elevation:10 m) is 50 kPa. At section S2 (elevation:12 m) the pressure is 20 kPa and velocity is 2 ms^-1. Density of water is 1000 kgm^-3 and acceleration due to gravity is 9.8 ms^-2. Which of the following is TRUE

While measuring the velocity of air ρ = 1.2 kg/m³, the difference in the stagnation and static pressure of a Pitot-static tube was found to be 380 Pa. The velocity at that location in m/s is

If a fluid jet discharging from a 50 mm diameter orifice has a 40 mm diameter at its vena contracta, then its coefficient of contraction will be
