Consider atmospheric air at 20°C and a velocity of 30 m/s flowing over both surfaces of a 1‐m‐long flat plate that is maintained at 130°C. Determine the rate of heat transfer per unit width from the plate for values of the critical Reynolds number corresponding to 105, 5 × 105, and 106.

q = 8472.2 W/m

Explanation:

The solving or solution is given in the attach documents.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
