Meclianical Equivalent of Heat. \

It has also been shewn that the heat losses take place nmiiily from 

 ■the tubes which lead the water into the flask iuul not from the fla»k 

 itself. For a fixed rate of generating heat the loss of heat is 

 -proportional to the excess of the mean of the inl«tt and outlet water 

 temperatures over the air temperature. The rate of loss of heat vnrieK 

 with the rate of generation of heat for fixed temperatures and has 

 been shewn to be a linear functicm of it. This will enable the heat 

 Josses to be allowed for. J.K.ll. I
