The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown in the Figure. The elevation differences are h₁=0.1m, h₂=0.1m, and h = 0.1m. The density of water, oil, and mercury are p_=1.0x10³kg/m³, p=0.85×10³ kg/m³, p = 13.6× 10³ kg/m³, respectively. The gravitational acceleration is g=9.81m/s².

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
