A bird is flying in a room with a velocity field of V (u, v, w) = 0.6x i + 0.2t j - 1.4 k (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 10 seconds of flight, as it flies through x = 1 m.

Hydrogen Energy

Energy is a quantity that cannot be defined, its existence can only be felt. In simple language, if a system possesses energy, it can do a specific kind of work. There are many forms of energy sources which people can use to obtain work. Solar energy, tidal energy, hydroelectric energy, geothermal energy, wind energy are some of the renewable energy sources which are primarily used for the production of electricity.

As shown in the figure below, two reversible cycles arranged in series each produce the same net work, Wcycle. The first cycle receives energy QH by heat transfer from a hot reservoir at TH= 1000°R and rejects energy Q by heat transfer to a reservoir at an intermediate temperature, T. The second cycle receives energy Q by heat transfer from the reservoir at temperature T and rejects energy Qc by heat transfer to a reservoir at Tc = 400°R.
