JSSC JE CE _Fluid Mechanics_Quiz-3

The tank of liquid (glycerin at 20°C with its density of 1260 kg/m³) in the adjacent figure, accelerates to the right with the fluid in rigid-body acceleration in m/s² would be

Triangular notch is preferred over rectangular notch because

A conical tube of length 2m is fixed vertically with its smaller end upwards. The velocity of the flow at the smaller end is 5m/s while at the lower end it is 2m/s. The pressure head at the smaller end is 2.5m of liquid. The loss of head in the tube is .What will be the pressure head at the lower end if the flow occurs in the downward direction?

Sharper crest of an ogee spillway

Bernoulli’s equation is applied to:

A venturimeter, having a diameter of 7.5 cm at the throat and 15 cm at the enlarged end, is installed in a horizontal pipeline of 15 cm diameter. The pipe carries an incompressible fluid at a steady rate of 30 litres per second. The difference of pressure head measured in terms of the moving fluid in between the enlarged end and the throat of venturimeter is observed to be 2.45 m. Taking the acceleration due to gravity as 9.81 m/s², the coefficient of discharge of the venturimeter (correct up to two places of decimal) is

Water flow in large sized pipes for large flow rates can be measured using:

The weir is always aligned at right angle to the direction of the river flow because

The flow in the section of a conduit shown in adjacent Figure is a:

Consider the following statements:

A) Pitot tube is used for measuring velocity of flow in the pipe.

B) Manometer is used for measuring fluid pressure in a pipe.

C) Venturimeter is used for measuring discharge in a pipe.
