1. The problem statement, all variables and given/known data
As part of a design task I'm doing for regional aircraft, I need to establish a Power Available/Power Required comparison.
On the plot, there are 2 lines...
Power Required (as a function of Velocity)
Power Available (as a function of Velocity)
basically, I have the required data. My propellor of choice is the PW150a.
The only data I can find is the Shaft Horsepower: 6200 - this is the 'takeoff, ISO value'

How do I turn this into a curve which varies with velocity
2. Relevant equations
thrust_req=c_d*m*g./c_l;
power_req=thrust_req.*V;
