Dittus-Boelter equation, NNu=0.023 (NRe) (NPr)n, where n = 0.4 for hot fluid and n = 0.3 for cold fluid, is applicable for
In forced convection the heat transfer depends on
The Fourier number (N) is defined as
The thermal diffusivity of a material is defined as
When heat is transferred by a chain of molecules from the hot area of an object to a colder area, the process of heat transfer is called
Cavitation in centrifugal pumps is caused by
