The speed of sound (a) is equal to the square root of the ratio of specific heats (g) times the gas constant (R) times the absolute temperature (T). The derivation of this equation is given on a separate page. Notice that the temperature must be specified on an absolute scale (Kelvin or Rankine). calculator developed by- Pawan Indalkar

– D. Raymer – Aircraft Design. A Conceptual Approach (1992) Wf​: Weight of the fuel required for the mission. Wo​: Initial takeoff weight of the aircraft. Wx​: Weight of the aircraft after completing the mission (excluding fuel weight). The factor 1.06 accounts for a typical 6% reserve and trapped fuel allowance.

In aircraft design, the lift formula is a fundamental equation used to calculate the lift force generated by an airfoil (such as a wing) as it moves through the air. The lift force is what enables an aircraft to overcome gravity and achieve flight. The lift formula is typically expressed as: Where: L is the
The Flow Mach Number (M) is a dimensionless parameter used to characterize the speed of an object moving through a fluid, particularly in the context of compressible flow like in aerodynamics M is the Flow Mach Number. V is the velocity of the object. a is the local speed of sound in the fluid.
