Internal Forced Convection

Please see the attached file for the completely formatted problem(s). Steam is condensed by cooling waterflowing inside copper tubes. The average heat transfer coefficient and the number of tubes needed are to be determined.

Internal Forced Convection

Please see the attached file for the completely formatted problem(s). The flow through a specified water oioe is given. The pressure drop and pumping requirements are to be determined.

Natural Convection

Please see the attached file for the completely formatted problem(s). A hot plate with an insulated back is considered. The rate of heat loss by natural convection is to be determined.

Radiation Heat Transfer

Please see the attached file for the completely formatted problem(s). Top and side of a cubical furnace are blackand are maintainedat uniform temperatures. Net radiation heat transferrate to the basefrom the top and side surfaces are to be determined.

Radiation Heat Transfer: Coal Bricks to Steaks

Please see the attached file for the completely formatted problem(s). A circular grill is considered. The bottom of the grill is covered with hot coal bricks, while the wire mesh on top of the grillis covered with steaks. The initial rate of radiation heat transfer from coal bricks to the steaks is to be determined.
