What is the expression for the maximum theoretical value of the nozzle outlet velocity (ve) with an infinite expansion, if γ represents the ratio of specific heats, To represents the chamber temperature, R is the gas constant? |
| A. | ve = \(\sqrt{(2\gamma RT_o(\gamma-1))}\) |
| B. | ve = \(\sqrt{(2\gamma RT_o/(\gamma-1))}\) |
| C. | ve = \(\sqrt{(2(\gamma+1)RT_o/(\gamma-1))}\) |
| D. | ve = \(\sqrt{(2(\gamma-1)RT_o(\gamma+1))}\) |
