K in newton's law of cooling
WebLaw of Cooling dT/dt = k (T (t) − 44) If we let y (t) = T (t) − 44, we have y (0) = T (0) − 44 = 72 − 44 = 28, so our differential equation becomes dy/dt = ky ; y (0) = 28 so, y (t) = y (0)ekt = 28ekt Because after 30 minutes the temperature has dropped to 61oF, we have y (30) = 61 − 44 = 17, so 28e30k = 17 17 Solving, we get = 28 ≈ −0.01663. WebRather than use Newton’s law of cooling in this form, it is often helpful to examine the behavior of the temperature of an object as a function of time while it is cooling. Eq. 1 is a differential equation with solutions for a cooling object as shown in Eq. 2, where T 0 is the initial temperature of the system when it begins to cool. () 0 t T ...
