A cylindrical rod having temperature T_(1) and T_(2) at its ends. The rate of flow of heat is Q_(1) cal//sec . If all the linear dimensions are doubled keeping temperature constant, then rate of flow of heat Q_(2) will be

In Q.No.4-49, the lowest rate of flow of heat is for:

Rate of heat flow through a cylindrical rod is H_(1) . Temperatures of ends of rod are T_(1) and T_(2) . If all the dimensions of rod become double and temperature difference remains same and rate of heat flow becomes H_(2) . Then (H_(1))/(H_(2)) is 0.x . Find value of x.

The ends of a metal rod are kept at temperatures theta_1 and theta_2 with theta_2gttheta_1 . The rate of flow of heat along the rod is directly proportional to

The two ends of a metal rod are maintained at temperature 100^(@)C and 110^(@)C . The rate of heat flow in the rod is found to be 4.0 J//s . If the ends are maintained at temperature s 200^(@)C and 210^(@)C . The rate of heat flow will be

The two ends of a metal rod are maintained at temperatures 100^(@)C and 110^(@)C . The rate of heat flow in the rod is found to be 4.0 j//s . If the ends are maintaind at temperatures 200^(@)C and 210^(@)C , the rate of heat flow will be :

If the end of metal rod is heated then the rate of flow the heat does not depend on

The ends of a metal rod are kept at temperature theta_(1) and theta_(2) with theta_(2) gt theta_(1) . At steady state the rate of flow of heat along the rod is directly proportional to
