a lump of steel weighing 30kg at a temp of 427 degree celcius is dropped into 150kg of oil at 27 degree celsius. The specific heat capacity of the steel and the oil are 0.47 KJ/KgK and 2.5 KJ/KgK



Activity:

0.01 kg of a certain perfect gas occupies a volume of 0.003m3 at a pressure of 7 bar and a temperature of 131°C. Calculate the molar mass of the gas. When the gas is allowed to expand until the pressure is 1 bar the final volume is 0.02m3. Calculate the final temperature.



Calculate the probability of finding the particle
between x= 0 to x=L/100, in an infinite potential
well of 10 Angstrom width. Given that the particle is in 100 th excited state.

A quality governed four stroke, single cylinder gas engine has a bore of 146 mm and a stroke of 280 mm. At 475 rev/min and full load the net load on the friction brake is 433 N, and the torque arm is 0.45 m. The indicator diagram gives a net area of 578 mm2 and a length of 70 mm with a spring rating of 0.815 bar per mm. Calculate the indicated power, the brake power and the mechanical efficiency.
