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.
A researcher would like to perform an experiment in a zero magnetic field, which means that the field of the earth must be cancelled. What current is needed in the solenoid's wires
what is the electrostatic force that acts on this charge. What would be the least speed required for the rest of the trip to arrive in time for the interview.
