Thanks I understood, thanls for answering and explain to me. In fact I'am in first year college and with this coeff and knowing the drag force formula, I could developp my first program applied to physics. Only giving analysis data, with several car coeff. (graphic of the Drag Force vs Speed...

In the Reynold Number http://en.wikipedia.org/wiki/Reynolds_number where: is the mean velocity of the object relative to the fluid (SI units: m/s) L is a characteristic linear dimension, (travelled length of the fluid; hydraulic diameter when dealing with river systems) (m) μ is the...

... and hte area considered is the area "touched" by the fluid, if I understood

Thansk for answering, so it is impossible to calculate this Area (Front of the vehicule) by myself ? cars having a irregular shape, isn't ?

Ok but in the same conditions, what makes a half sphere have a lesser drag coeff than a sphere ?

... and excuse my english I'm french

Hi ! First at all thanks for read, I'm new in the forum ... So the problem is, I would calculate the drag coeff of a car but in the coeff formula I would like to know which AREA is considered for this. drag coeff is given by = 2F / ρ(V^2) A Where : F is the drag force ρ is the mass...

Thanks great videos
