Statement (I) : Piston temperature profiles near full load are flattened in case of liquid cooled engines whereas for air cooled engines temperature profiles are steeper. Statement (II) : The piston temperature profiles are different in nature for liquid cooled and air cooled engines because of the different values of ehat capacities.(a) Both Statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I) (b) Both statement (I) and Statement (II) are individually true but Statement (II) is NOT the correct explanation of Statement (I) (c) Statement (I) is true but Statement (II) is false (d) Statement (I) is false but Statement (II) is true |

Answer» (d) Statement (I) is false but Statement (II) is true The air cooling system for piston is likewise the fin cooling system in which cooling temperature profile is exponential curve not steeper curve. So, statement I is false. Also, liquid cooling system use convective type of cooling in which curve can not be flatten. As different phenomenon is happening for cooling in two different process because of change in heat transportation media and hence heat capacities of cooling fluid. |
