RESULTS – HEAT TRANSFER EQUATION Specific Heat of Steel= .452 kJ/(kg*K) Temperature Change= ∆ T=10K=10°C Mass=.284 kg Q= mC∆T The above equation is used to calculate the amount of power need to change temperature in a specific material. =.284kg*.452kJkg*K*10K=1.288 kJ The equation uses the specific heat of steel, the temperature change of the blade from 23F to 41F and the weight of the average steel blade. Assume time(t)= 180s P=1.28kJ/180s*1000=7.13 W
