The power required at the pedals of these cycles at any speed on a level, smooth, hard surface, in still air can be expressed as:(adsbygoogle = window.adsbygoogle || []).push({});

W = Cv [K1 + K2 (Cv + Cw) ©÷ + 10.32 ¥Òm (s/100 + 1.01a/g)]

I found this equation, but I don't get what K1 and K2 is

Cw ¡æ speed of headwind in m/s

¥Òm ¡æ total mass of the rider + clothing + bicycle in kg

a/g ¡æ bicycle¡¯s acceleration as a proportion of gravitational acceleration

Does anybody know what K1 and K2 are?

Thanks in advance! :)
