A pilot wants to fly his aeroplane in atmosphere free space 

The height of mercury which exerts the same pressure as 20 cm of a water column, is equal to

If the surface tension of water is $$0.06N/m$$, then the capillary rise in a tube of a diameter $$1mm$$ is :($$\theta={0}^{o}$$)

If the meniscus of a liquid is concave in shape, then

In steady horizontal flow:

Pressure (P) exented by liquid on walls of the container when h = height of the liquid column, f = density, g is acceleration due to gravity

The SI unit of hydro-static pressure is :

Choose the correct option. Consider tube to be made of glass.

Bernoulli's equation is applicable to points :

 1 mm Hg is equal to
