A long solenoid has 100 turns/cm and carries current i. An electron moves within the solenoid in a circle of radius 2.40 cm perpendicular to the solenoid axis. The speed of the electron is 0.040 c (c = speed of light). Find the current i in the so
If these readings are 333K and 138kPa, respectively, and the static pressure is 101.3 kPa, calculate Mach number, static temperature, and air velocity at the instrumented station.
For this case, assume that the pressure losses in the injector etc. are neglected. Determine required mass ratio given hydrazine Isp, make sure that the numbers add up.
