sir velocity traingle wala quest direct formula se kr sakte h kya ???
sir plz check that angle in velocity diagram which u have taken will be 90-theta
The solution is correct, see the velocities and the configuration diagram and you will understand.

sir plz discuss other 2 marks questions previous years with ur approach fluid and thermal section it would help all of us
this is the course which is going to be very helpful in these days before gate examination. thanks keep it your dhristhi on us..:)

  2. One kg of an ideal gas (gas constant, R 400 J/kg.K; specific heat at constant volume, c-1000J/kg K) at 1 bar, and 300 K is contained in a sealed rigid cylinder. During an adiabatic process, 100 kJ of work is done on th a stirr The increase in entropv of the system is J/K

  6. the magnitude of angular velocity (upto 3 decimal points accuracy) of the crank is For an inline slider-crank mechanism, the lengths of the crank and connecting rod are 3m and 4m, respectively. At the instant when the connecting rod is perpendicular to the crank, if the velocity of the slider is 1 m/s, radian/s.

  9. Moist air is treated as an ideal gas mixture of water vapor and dry air (molecular weight of air Given that the saturation pressure of water at 30 C is 4246 Pa, the mass of water vapor per kg of dry air is 28.84 and molecular weight of water = 18). At a location, the total pressure is 100 kPa, the temperature is 30 C and the relative humidity-ts55 grams.
