Hamwi Formula

Hamwi Formula. Ibw [kg] = 22 × height[m] 2. 48.0 kg + 2.7 kg per inch over 5 feet;

Ideal body weight (in kilograms) = 45.5kg + 2.2kg for each inch over 5 feet To determine body weight in pounds, the desired bmi is multiplied by 5 and then add bmi/5 lb for each inch >5 ft in height. Add 10% if person has large frame, subtract 10% if person has small frame.

Parasite Drag Formula

Parasite Drag Formula. Rho stands for the air density while s stands for the total area. Example plots are given showing drag divergence mach number using each equation with contours of quarter chord sweep angle at 0°, 15°, 30°, 45°, 60°, and 75° utilizing the following inputs:

So, drag area is defined as the product of the drag coefficient created by attributed to the particular body or a particular component multiply by its area. Form drag known also as pressure drag arises because of the shape and size of the object. This equation is simply a rearrangement of the drag equation where we solve for the drag coefficient in terms of the other variables.
