If the atmospheric pressure at sea level is 7.5 N/cm2, determine the pressure at a height of 3000m assuming the pressure variation follows isothermal law. The density of air is given as 1.2 km/m3.
The barometric pressure at sea level is 760 mm of Mercury while that on a mountain top is 715 mm. If the density of air is assumed constant at 1.2 kg/m3 , what is the elevation of the mountain top?

Calculate the pressure at a height of 6500m above the sea level if the atmospheric pressure is 10.145 N/cm2 and temperature is 25℃ assuming air is incompressible. Take density of air as 1.2 kg/m3. Neglect variation of g.
Calculate the pressure of air at a height of 3500m from sea level where pressure and temperature of air are 10 N/cm2 and 25℃ respectively. The temperature lapse rate is given as 0.0065 ℃ /m. Take density of air at sea level equal to 1.2 kg/m3.
Pressure variation for compressible fluid is maximum for which kind of process?
Why can’t the density be assumed as constant for compressible fluids?
What is the variation observed in temperature in atmosphere with respect to elevation?
As we go upwards, at height there is slight decrease in pressure variation.
For dynamic fluid motion in a pipe, the pressure measurement cannot be carried out accurately by manometer.
A simple U tube manometer connected to a pipe in which liquid is flowing with uniform speed will give which kind of pressure?
