The top surface of a heated compartment consists of very smooth (a) and highly roughened (b) portions, and the surface is placed in an atmospheric airstream. in the interest of minimizing total convection heat transfer from the surface, which orientation, (1) or (2), is preferred? if ts = 100℃, t[infinity] = 20℃, and u[infinity] = 20 m/s, what is the convection heat transfer from the entire surface for this orientation? 7.34

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

no sign of dia of fuel cell

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
