Moment of inertia is not only dependent on amount of matter. It also depends upon position of axis of rotation and shape of matter. (Formula: L=I?). Thus, inertia and angular speed play an important role in determining angular momentum.

The velocity profile for Poiseuille flow is zero at eir side of channel and non-zero in middle. Therefore, Quadratic equation is only possible option here.

Pitot tube is used for velocity measurement or airspeed measurement of an aircraft. Placing a pitot tube behind jet engine will give us speed of gas rejected by jet engine instead of airspeed, hence, giving us erroneous readings. The best placement would be at a point where speed of air is closest to airspeed as seen by aircraft.

When re is a high rate of fluid flow, molecules tend to collide with each or. At this state, average translational kinetic energy of particles increases. The temperature developed due to this is called as Kinetic temperature.

Q = 2/3 Cd *b*?2g* (H2^1.5 ? H1^1.5)
Here,
H1 = 3.8
H2 = 2.5
b = 2.2
Hence, Q = 13.9 m3/s.

The Froude number is a dimensionless number. It is defined as ratio of flow inertia to external field. The Froude number is based on speed-length ratio.

Alcohol is an organic compound on which a hydroxyl functional group is bounded to a saturated carbon atom. Alcohols work as an antifreeze solution at cool temperatures. Thus, it is not a magneto fluid.

One dimensional flow is a flow in which variations of velocity and pressure occur along one space coordinate only. A good example of one dimensional flow is a flow through pipe. During a flow through a pipe, functions of velocity and pressure occur along length of pipe.

The Pitot tube readings are more accurate than Orificemeter.

Piezometric head is addition of pressure head and datum head. The pressure head is given by P/?g = 20.4 m. The datum head is 2 m, which makes it a total of 22.4 m. The velocity given is extra information.
