Specific Heat of water(CP)=4.2 KJ/kg⁰C Thermal conductivity of water=k=0.58 W/mK Viscocity of water at 30⁰C -40⁰C= 0.798 E-3Ns/m2. The Basic Design Equation and Overall Heat Transfer Coefficient The basic heat exchanger equations applicable to shell and tube exchangers were developed in Chapter 1. Helical coil heat exchangers (HCHEs) are widely used in several heat transfer applications such as steam generators, refrigerators, nuclear reactors, chemical plants and domestic hot water systems (DHW) due to their compactness in structure, ease of manufacture, maintenance and improved thermal efficiency. Heating air with a steam coil or a hot water coil is an example of sensibly heating air. Quality Policy.
