Properties of air For ideal gases, the properties cρ, k, µ, and Pr are independent of pressure. The properties ρ, ν, and α at a pressure P (in atm) other than 1 atm are determined by multiplying the values of ρ at the given temperature by P and b
Air at a pressure of 1 atm and a temperature of 50°C is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 100°C. The plate has a length of 0.20 m (in the flow direction) and a w...

In June and August 1657, the Accademia del Cimento began to perform numerous experiments involving Torricelli's barometer and questioning traditional beliefs about the pressure of air and the impossibility of the void. One could conduct an investigation of the academicians'work in this field relying...
A vessel of volume 50 litre contains an ideal gas at0∘C. A portion of the gas is allowed to leak out from it under isothermal conditions so that pressure inside falls by 0.8 atmosphere. The number of moles of gas leaked out is nearly: ...
