01.Poise is a unit of –

02.Bourdon gauge is used to measure

03.Langrangian method of fluid study is also

04.When a fluid flows in a curved path without any external force the fluid motion is called
Free vortex flow.
05.Which of the following can be used to measure velocity in open channel flow.
Current meter.
06.Which of the following is CORRECT about the viscosity of gas?
Increases with an increase in the temperature.
07.Runaway speed of a hydraulic turbine is
The speed if the turbine runner is allowed to revolve freely without load and with the wicket gates wide open.
08.The flow in which the velocity vector is identical in magnitude and direction at every point, for any given instant, is known as
uniform flow.
09.If for a fluid in motion, the pressure at a point is same in all directions, then the fluid is
An ideal fluid.
10.The property of a working system which changes as the heat is supplied to the working fluid in a reversible manner is known as.
Entropy.
11.The heat rejection takes place in Carnot cycle at _______.
isothermal compression.
12.Which gas can attain the highest efficiency for the same compression rise?
Mono atomic gases.
13.Specific heat of a gas, Cp = Cv, at
Absolute zero.
14.A thermometer works on the principle of
Zeroth law of thermodynamics.
15.Carnot cycle consists of
Two isothermal and two isentropic processes.
16.Which one of the following is extensive property of a thermodynamics system
Volume.
Explanation:-
Intensive Property: These are the properties of system which are independent of mass under consideration. Just like e.g. Pressure, Temperature, density.etc
Extensive Properties: The properties which depend on the mass of system under consideration.
Just like e.g
Internal Energy, Enthalpy, Volume, Entropy.etc
Remember All specific properties are intensive properties.
For e.g. specific volume, specific entropy etc.
Since volume depends on mass hence it is extensive property.
