bird is flying in a room with a velocity field of V?=(u, v, w)=0.6x+0.2t–1.4 (m/s)V?=u, v, w=0.6x+0.2t–1.4 m/s . The room is heated by a heat pump so that the temperature distribution at steady state is T(x,y,z) = 400 – 0.4y – 0.6z – 0.2(5 – x)2 (°C). Calculate the temperature change that the bird feels after 8 seconds of flight, as it flies through x = 1 m. The temperature change that the bird feels after 8 seconds of...
