10-cm-thick brass plates (k = 110 W/m‧K, rho= 8530 kg/m3 , cp = 380 J/kg‧K, α= 40 x 10-6 m2 /s) are cooled in an impinging jet of air at 15 o C and convective heat transfer coefficient of 220 W/m2 ‧K. The plate is initially at a uniform temperature of 600 o C and the bottom is insulated. Determine the temperature of plane that is 5 cm from the top surface after 3 minutes of cooling.

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
