Question

The unit of specific heat is ft/kg.

(a) True

(b) False

I got this question during an internship interview.

The origin of the question is Minimum Fuel Climb topic in division Climb and Descent Performance of Aircraft Performance

Answer 1

Right choice is (a) True

For explanation I would say: The formula for specific climb is given by SC=\(\frac{dH/dt}{Q_f}\) where SC is specific thrust, \(\frac{dH}{dt}\) is rate change of height with respect to time and Qf is fuel flow. The specific climb is calculated in the units of ft/kg.
