One calorie is defined as the heat required to raise the temperature of 1 gm of water by 10C in a certain interval of temperature and at certain pressure. The temperature interval and pressure is
A rocket motor has a chamber pressure of 100 bar and chamber temperature of 3000 K. The ambient pressure is 1 bar. Assume that the specific heat at constant pressure is 1 kJ/kg-K. Also assume that the
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.
Statement:All patients with high blood pressure were found to be having some worry or the other.Conclusions:I. Mental tensions may affect blood pressure.II. If one has no mental tensions one may not s
A gas at pressure P is adiabatically compressed so that its density becomes twice that of initial value. Given that the ratio of specific heats at constant pressure and constant volume is 7/5. What wi
The vapour pressure of pure liquid A is 70 torr at 27 degreeCentigrade. It forms an ideal solution with another liquid B. The mole fraction of B is 0.2 and total pressure of the solution is 84 torr at
lf the systolic pressure is 120 mm Hg and diastolic pressure is 80 mm Hg, the pulse pressure is ______
