Preview:Round Duct Heat Transfer Coefficient and Wall Temperature Calculator Tube wall temperature(Tw)is calculated as: Tw= Tb+ q / (h A) h = Nu · k / D The Nusselt number is calculated as: For Laminar Flow - Re < 2300 Nu = 4.36 for uniform surface heat flux conditions friction f ...
By adding a lumped stray capacitance in parallel, this equivalent circuit tries to mimic the frequency response of the coil impedance. This will be accurate only for a limited band of frequencies centred around the design frequency.What can this calculator be used for?
