The Bernoulli’s equation refers to conservation of
Bernoulli’s equation refers to conservation of energy.
How are the velocity coefficient Cv, the discharge coefficient Cd and the contraction coefficient Cc of an orifice related
The relation between Cd, Cc and Cv is
Cd = CcCv
The coefficient of velocity (Cv) for an orifice is
The equation of motion for a viscous fluid known as
In Navier-Stokes equation pressure force, gravity force and viscous force are considered.
The rate of flow through venturimeter varies as
Rate of flow through a venturimeter is given 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
Applying Bernoulli’s equation between section S1 and S2
as area is constant velocity head will be same
thus flow from S1 to S2 and head loss is 1.06 m.
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
