2.42. A flow calorimeter like that shown in Figure 2.6 is used with a flow rate of 20 g-min-1 of the fluid being tested and a constant temperature of 0°C leaving the constant- temperature bath. The steady-state temperature at section two (T,) is measured as a function of the power supplied to the heater (P), to obtain the data shown in the table below. What is the average specific heat of the substance tested over the temperature range from 0°C to 10°C? What is the average specific heat from 90°C to 100°C? What is the average specific heat over the entire range tested? Describe how you would use this data to derive an expression for the specific heat as a function of temperature. |T2/°C 10 20 30 40 50 60 70 80 90 100 P/W 5.5 11.0 16.6 22.3 28.0 33.7 39.6 45.4 51.3 57.3 Actual velocity profile Control volume V, U.
