The pressure intensity of a liquid is same in all directions only when

The minor loss due to sudden contraction is due to

Single stage centrifugal pump delivers 1 m³/s of water against net head of 16 m. What is specific speed of pump if it runs at 800 rpm?

Which of the following is correct dimension for dynamics viscosity(µ)?

For open channel flow best hydraulic section is

The discharge in an open channel is generally measured by

Which of the following statement(s) is/are true for Prandtl Mixing Length?

(i) It is that distance between two layers in the transverse direction such that lumps of fluid particles from one layer could reach the other layer and the particles are mixed in the other layer in such a way that the momentum of the particles in the direction of x is same

(ii) It is zero at the pipe wall

The specific speed value for a turbine is the speed of a geometrically similar turbine which would

An irrigation canal has a steady discharge Q at a section where a cross regulation (gate) is provided for control purposes. If the gate of the regulator, which is normally fully open, is suddenly lowered down to a half open position then a rapidly varied unsteady flow results. In such a case, it would take the form of a

The magnitude of water hammer depends upon the

(i) Elastic properties of pipe material.

(ii) Elastic properties of liquid flowing through the pipe.

(iii) Speed at which the valve is closed.
