A diesel engine has an air temperature and pressure at the beginning of the compression stroke of 290K and 220 kPa, respectively (State 1). At the end of the heat addition process the temperature and pressure are 1550K and 7200 kPa, respectively. Compute the following: (a) the temperature at the end of the compression process, (b) the volumetric compression ratio, (c) the temperature at the end of the expansion process, (d) the cycle thermal efficiency, and (e) the mean effective pressure. Assume air to be an ideal gas with Cp, o=1.004 kJ/(kg K) and Cv, o=0.717 kJ/(kg K).

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
