Design a converging-diverging nozzle for a spacecraft thruster that has an exit Mach number of 5.00 when using compressed helium at 50.0 MPa, and 0.00°C. Assume the nozzle exhausts into a total vacuum.
Plot the nozzle diameter vs. length along the nozzle, keeping the angle of the diverging wall to less than 10o with the horizontal to prevent flow separation.
Show the positions along the nozzle where M = 1, 2, 3, 4, and 5. Determine the mass flow rate through your nozzle.
A shaving/cosmetic mirror is designed to magnify your face by afactor of 1.3 when your face is placed 20.0 cm in front of it. what is the focal length and the radius of curvature of the mirror
Three moles of nitrogen gas,N2, at 31.0°C arecontained in a 19.5 L cylinder. Find the pressure the gas exerts on the cylinder walls
In the circuit below, the current through B is 1.50 A and the current through C is 0.50 A when A has a resistance of 9 Ω. If you replace A with a 27 Ω resistor, the current through B reduces to 0.75 A and C to 0.25 A. Hint: The voltage drop across..
