The value of momentum correction factor (β) for a laminar flow through a circular pipe, is
Momentum correction factor is defined as the ratio of momentum of the flow per second based on actual velocity to the momentum of the flow per second based on average velocity across a section. For turbulent flow the momentum correction factor is slightly higher than one near to 1.2 and for laminar,Read more

A manometer is a device that we use to measure the pressure of the pipelines (cab be of gas, water, liquid, etc.) Also, it is usually referred to as a U-shaped tube that is filled with a liquid.

See lessThe equation for the viscosity, is suggested
This formula also shows that this all equals F/A. Recall that viscosity is equal to force divided by area; the F refers to force and the A refers to area. Therefore, F/A is another way to refer to viscosity.

See lessIn an open tube, free surface of mercury remains
Explanation: Assuming the test tube is made of glass, the mercury has obtuse angle of contact. Hence, the outer surface will be convex, unlike water (which has concave surface due to acute contact angle).

See lessMost economical section of a triangular channel, is
In the most economical triangular section, the side slope has to be inclined at 45∘ or the hydraulic radius has to be 1 2 2 times the depth of flow. The width of the channel is twice the depth of flow. Hydraulic radius is half of the depth of flow.

See lessEuler's equation for motion of liquids, is given by
Euler's Equation, proposed by Leonhard Euler in the mid-18th Century, is a vital equation in fluid mechanics that describes the flow of inviscid fluid. Here, inviscid fluid refers to an ideal fluid with zero viscosity.

See lessAn ideal flow of a liquid obeys
An ideal flow of any fluid must fulfill the “Continuity equation”. The continuity equation applies to all fluids whether incompressible (ideal) or compressible (non-ideal), Newtonian or non-Newtonian fluids.

See lessA pipe of 0.1 m2 cross sectional area suddenly enlarges to 0.3 m2 cross-sectional area. If the discharge of the pipe is 0.3 m3 /sec, the head loss is
The velocity in the larger pipe is: v2 = Q / A2 = 0.3 m^3/s / 0.3 m^2 = 1 m/s h(en) = (v1 - v2)^2 / 2g = (3 m/s - 1 m/s)^2 / 2 * 9.81 m/s^2 = 2/g meters of water Therefore, the head loss is 2/g meters of water.
The velocity in the larger pipe is:
v2 = Q / A2 = 0.3 m^3/s / 0.3 m^2 = 1 m/s
h(en) = (v1 – v2)^2 / 2g = (3 m/s – 1 m/s)^2 / 2 * 9.81 m/s^2 = 2/g meters of water
Therefore, the head loss is 2/g meters of water.
