A flow calorimeter like is used with a flow rate of 
of the fluid being tested and a constant temperature of 0°C leaving the constant - temperature bath. The steady-state temperature at section two 
is measured as a function of the power supplied to the heater (P), to obtain the data shown in the table below.
