Q1. Air at a pressure and a temperature of 1 atm and 50 c, respectively, is in parallel flow over the top surface of a flat plate the is heated to a uniform temperature of 100 c. the plate has a length of 0.20-m (in the flow direction)and a width of 0.1m.the reynold based on the plate length is 40000.what is the rate of heat transfer from the plate to the air? If the free stream velocity if the air is doubled and the pressure are increased to 10 atm, what is the rate of heat transfer?

Q2. A 10.0g bullet is fired horizontally into a 105g wooden block that is initially at rest on a frictionless horizontal surface and connected to a spring of constant 152N/m. The bullet becomes embedded in block. If the bullet-block system compresses spring by a maximum of 76.0cm, what was the speed of the bullet at impact with block?
