Q. An IC engine is operating on the cycle shown below. The cycle takes in air at 1 bar and 300 K. The air is compressed isothermally and then heated at constant volume so that the pressure rises to 15 bar and temperature to 700 K. The air expands isothermally to its initial volume and rejects the cycle. What is the mean effective pressure

Q. Why was there a military operation carried out to take back Goa from the portuguese?
