recalling :)... Drag = 1/2 A * Cd * rho *vsquared A = frontal area (any one know this for Vanagon/Westy?) Cd = drag coeffficient, I have seen 0.44 stated for Vanagon rho = density of air Density of air at sea level = 1.226 kg/cubic meter.
We should be able to estimate
something! from above equation if we ignore rolling/mech resistance. Usually we can say that those factors are constant over limited speed range. At least one can get the minimum power required to go a given speed. Alistair -- '82 Westy -> diesel converted to gas in '94 albell@uvic.ca http://members.shaw.ca/albell |
