The heat-transfer coefficients to monoisopropylbiphenyl and biphenyl during variations in the process parameters were determined, and the results were compared with theoretical equations of different types. These coefficients were determined during turbulent flow in tubes without a change in the state of aggregation of the organic fluids. The heat-transfer coefficients to monoisopropylbiphenyl were determined at heat fluxes of 200,000, 500,000, and 860,000 Kcalsq m hr and at circulation rates of 4, 6, 10 and 15 msec., and those to biphenyl were determined at a heat flux of 300,000 Kcalsq m hr and circulation rates of 4 and 6 msec. Under these conditions, the Reynolds number was found to fall within 25,000 - 420,000, and the heat-transfer coefficient varied from 3,000 to 18,000 Kcalsq m hr deg. C.
