Primary fluid enters the heat exchanger of a nuclear facility at 610 F and leaves at 540 F. The flow rate is approximately 1.38 x 108 lbm/hr. If the specific heat if the fluid is taken 1.5 Btu/lbm F.
M dot. X cp x delta T is the heat transferred They give you everything , 70 degrees delta T, cp is 1.5, and m dot is the 1.38 x 10^8. Units are handed to you no conversion required.
