Which of the following indicates the range formula in cruise method 2?(a) R=\(\frac{1}{C}\big(\frac{2}{\rho SC_L}\big)^{\frac{1}{2}}\int_{W_{i}}^{W_{f}}\frac{dW}{W^{\frac{1}{2}}}\)(b) R=\(\Big(\frac{2}{\rho SC_L}\Big)^{\frac{1}{2}}\frac{L}{D}\int_{W_{i}}^{W_{f}}\frac{dW}{W^{\frac{1}{2}}}\)(c) R=\(\Big(\frac{2}{\rho SC_L}\Big)^{\frac{1}{2}}\frac{LC}{D}\int_{W_{i}}^{W_{f}}\frac{dW}{W^{\frac{1}{2}}}\)(d) R=\(\frac{1}{C}\Big(\frac{2}{\rho SC_L}\Big)^{\frac{1}{2}}\frac{L}{D}\int_{W_{i}}^{W_{f}}\frac{dW}{W^{\frac{1}{2}}}\)The question was posed to me during an internship interview.The origin of the question is Cruise Method 2 in portion Cruising Performance of Aircraft Performance |
