A Thomas flowmeter is a device in which heat is transferred at a measured rate from an electric coil to a flowing fluid, and the flow rate of the stream is calculated from the measured increase of the fluid temperature. Suppose a device of this sort is inserted in a stream of nitrogen, the current through the heating coil is adjusted until the wattmeter reads 1.00kW, and the stream temperature goes from 35.0C and 110kPa before the heater to 43.8C and 110kPa after the heater. If the specific enthalpy of nitrogen is given by the formula H^(kJ/kg)=1.04(T(C)25.0) what is the volumetric flow rate of the gas (L/s) upstream of the heater (i.e. at 35.0C and 110kPa )? L/s
