The energy balance equation can be used to determine the heat transfer rate (Q) if the mass flow rates, specific heat capacities, and inlet and outlet temperatures of the two fluid streams are known. It can also be used to determine the outlet temperatures of the fluid streams if the heat transfer rate and the inlet temperatures are known.

Geankoplis 4th ed. 4.5‐4. Water flowing at a rate of 13.85 kg/s is to be heated from 54.5 to 87.8oC in a double‐pipe heat exchanger by 54,430 kg/h of hot gas flowing counterflow and entering at 427oC ( 1.005 / ).
An energy balance calculation is necessary to determine the heating and cooling duties in the flowsheet. An estimate of the heat content of each stream can be rapidly determined by making the following assumptions: 1. The vapor and liquid streams have ideal properties. Energy Balances – p.3/14
To begin modeling, start by solving the appropriate energy balance (either Equation \ref{2} or \ref{4}) for and make any simplifications necessary. Then use a method to solve ODEs in Excel, such as Euler's or Heun's.
Energy Balance for Closed Systems. Now that you have learned how to calculate the various forms of energy, kinetic, potential, and internal, and know how energy is transferred via heat and work, it’s time to put all of it together.
The same steam generator can also be analyzed by an energy balance on the primary flow stream with the equation \( \dot{Q} = \dot{m} ~c_p ~\Delta T \), where \( \dot{m} \), c p, and ΔT are the mass flow rate, specific heat capacity, and temperature change of the primary coolant. The heat transfer rate of the steam generator can also be ...
18 Μαΐ 2018 · This chapter presents the basic mass, momentum and energy conservation equations derived for the flowing medium, determination of the temperature distribution in the walls of tubes with a circular cross-section and with a complex shape, and determination of the heat transfer coefficient for non-finned and finned tubes.
