Minimum Flight Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Minimum Flight Velocity = sqrt((Aircraft Weight/Aircraft Gross Wing Area)*(2/(Air Density))*(1/Lift Coefficient))
V_min = sqrt((W/5)*(2/(ρ))*(1/C_L))
This formula uses 1 Functions, 5 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Minimum Flight Velocity - (Measured in Meter per Second) - Minimum Flight Velocity is the velocity of the aircraft such that air passes over the wings fast enough for the aircraft to sustain constant altitude.
Aircraft Weight - (Measured in Newton) - Aircraft Weight is the total aircraft weight at any moment during the flight or ground operation.
Aircraft Gross Wing Area - (Measured in Square Meter) - Aircraft Gross Wing Area calculated by looking at the wing from a top-down view and measuring the area of the wing.
Air Density - (Measured in Kilogram per Cubic Meter) - Air Density denoted ρ, is the mass per unit volume of Earth's atmosphere.
Lift Coefficient - The Lift Coefficient is a dimensionless coefficient that relates the lift generated by a lifting body to the fluid density around the body, the fluid velocity and an associated reference area.

STEP 1: Convert Input(s) to Base Unit

Aircraft Weight: 1800 Newton --> 1800 Newton No Conversion Required
Aircraft Gross Wing Area: 4 Square Meter --> 4 Square Meter No Conversion Required
Air Density: 1.293 Kilogram per Cubic Meter --> 1.293 Kilogram per Cubic Meter No Conversion Required
Lift Coefficient: 0.002 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_min = sqrt((W/5)*(2/(ρ))*(1/C_L)) --> sqrt((1800/4)*(2/(1.293))*(1/0.002))

Evaluating ... ...
