Stall velocity for given weight Solution

STEP 0: Pre-Calculation Summary
Formula Used
Stall Velocity = sqrt((2*Weight)/(Freestream Density*Reference Area*Maximum Lift Coefficient))
Vstall = sqrt((2*W)/(ρ*S*CL,max))
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
Stall Velocity - (Measured in Meter per Second) - Stall Velocity is defined as the velocity of an airplane in steady flight at its maximum lift coefficient.
Weight - (Measured in Newton) - Weight Newton is a vector quantity and defined as the product of mass and acceleration acting on that mass.
Freestream Density - (Measured in Kilogram per Cubic Meter) - Freestream density is the mass per unit volume of air far upstream of an aerodynamic body at a given altitude.
Reference Area - (Measured in Square Meter) - The Reference Area is arbitrarily an area that is characteristic of the object being considered. For an aircraft wing, the wing's planform area is called the reference wing area or simply wing area.
Maximum Lift Coefficient - Maximum Lift Coefficient is defined as the lift coefficient of the airfoil at stalling angle of attack.
STEP 1: Convert Input(s) to Base Unit
Weight: 60.5 Newton --> 60.5 Newton No Conversion Required
Freestream Density: 1.225 Kilogram per Cubic Meter --> 1.225 Kilogram per Cubic Meter No Conversion Required
Reference Area: 5.08 Square Meter --> 5.08 Square Meter No Conversion Required
Maximum Lift Coefficient: 0.000885 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Vstall = sqrt((2*W)/(ρ*S*CL,max)) --> sqrt((2*60.5)/(1.225*5.08*0.000885))
Evaluating ... ...

STEP 3: Convert Result to Output's Unit
148.224894299244 Meter per Second --> No Conversion Required
FINAL ANSWER
148.224894299244 148.2249 Meter per Second <-- Stall Velocity

Why does stall speed increase in a turn?

When you turn, you need to increase your total lift to maintain altitude. You increase your total lift by increasing your angle of attack, which means you're closer to stall than you were in wings-level flight. And, your stall speed increases in proportion to the square root of your load factor.
