A nozzle accelerates a helium current from 16 m/s to 95 m/s. The inlet temperature of the current is 35 °C and, during this process, the fluid receives 3.7 kJ/kg of heat from the hot surroundings. Assume the gas specific heat at constant pressure (????????) to be 1.8 kJ/(kg K). Determine the exit temperature of the fluid in °C to one decimal place.
