Movement of air due to difference in air pressure is
The pressure, temperature and velocity of air flowing in a pipe are 5 bar, 500 K and 50 m/s, respectively. The specific heats of air at constant pressure and at constant volume are 1.005 kJ/kgK and 0.
A room contains 35 kg of dry air and 0.5 kg of water vapor. The total pressure and temperature of air in the room are 100 kPa and 25°C respectively. Given that the saturation pressure for water at 25
The pressure, dry bulb temperature and relative humidity of air in a room are 1 bar, 30°C and 70%, respectively. If the saturated steam pressure at 30°C is 4.25 kPa, the specific humidity of the roo
A tube of length L and radius R is joined to another tube of length L / 3 and radius R / 2 . A fluid is flowing through this tube. If the pressure difference across the first tube is P, then the press
Three capillaries of internal radii 2r, 3r and 4r, all of the same length, are joined end to end. A liquid passes through the combination and the pressure difference across this combination is 20.2 cm
Air at 700C and 0.015 humidity ratio is cooled adiabatically by spraying water. The final temperature of the air is 550C. Specific heat capacities of dry air and water vapour are 1.005 and 1.88 kJ kg-
