Plate heat exchanger calculation example An example of a high specific heat is water’s specific heat, which requires 4.184 joules of heat to increase the temperature of 1 gram of. Determines the amount of heat that the unit gives off. The calculation of the heat load of the heat exchanger is carried out according to the formula P = m × cp × δt, where m means the flow rate of the medium, cp is the specific heat capacity, and δt is the temperature difference at the inlet and outlet of the circuit. Template name: Calculation of S&T heat exchanger area sizing. Template number: HCPE-MMP-0017. Purpose: This template calculates the size of an S&T heat exchanger. This should be treated as a quick check for budgetary proposals only. Actual heat exchanger design should be carried out in reputable software like HTRI or HTFS for actual procurement. Example: Find the final temperature of the mixture, if two cup of water having masses m1=150g and m2=250g and temperatures T1= 30 ºC and T2=75 ºC are mixed in an isolated system in which there is no heat lost. (cwater=1cal/g.ºC).

Because plate heat exchangers are used for transferring heat, they require inlets and outlets where the flowing mediums -or fluids - can enter and leave the heat exchanger. A fluid may be a liquid or a gas. As fluids are often assumed.
