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 1.25 kW, and the stream temperature goes from 32.5°C and 110 kPa before the heater to 40.0°C and 110 kPa after the heater. If the specific enthalpy of nitrogen is given by the formula i(wrne) = 104(7(*c) - 250) = 1.04 what is the volumetric flow rate of the gas (L/s) upstream of the heater (i.e. at 32.5°C and 110 kPa)?
