Web9 jul. 2006 · Hence, the wetted area is raised to a fraction of a power, for example A^0.82 is used to determine total heat input, btu/hr. What this means is you will get a lower heat input rate by considering your 3 exchangers as being one long exchanger because (3*24*37/12)^0.82 < 3* (24*37/12)^0.82. I believe the proper way to determine your heat … Web11 mrt. 2012 · The wetted surface of the rudder is greater. Note: Do not use "wetted" surface area when calculating the lift and drag force of a keel and rudder. Instead they use the average cord length ((root cord + tip cord)/2) times the span. This figure is 1/2 the value of the wetted surface equation provided by Eric. This area is sometimes called the ...
