Btu per pound of air transferred through the tube wall are to be calculated. Concept Introduction: The general energy balance equation is: Δ H ^ + ( u 2 2 − u 1 2 ) 2 g c J + g ( z 2 − z 1 ) = Q − W s m ˙ ...... (1) Here, u 1 and u 2 are the initial and final velocity of the system, z 1 and z 2 are the initial and final height of the system, Q is the heat of the system, W s is the shaft work, g c is the acceleration due to gravity, and J is the mechanical equivalent of heat. Δ H ^ is further defined as: Δ H ^ = C p ( T 2 − T 1 ) ...... (2) Here, C p is the specific heat of the species, and T 1 and T 2 are the initial and final temperature of the system.
