Experimental measurements on a new methane fuel nozzle for a furnace produce an exit velocity, pressure, and temperature for methane of 335 m/s, 0.100 MPa, and 0.00°C. The upstream stagnation pressure and temperature are 0.150 MPa and 22.0°C. Determine
a. The nozzle efficiency.
b. The nozzle's velocity coefficient.
c. The nozzle's discharge coefficient.
