The temperature of the water is 300 K. The specific volume of water is 0.001 m³/kg. The mass flow rate at the inlet is mi = 1 kg/s. The cross area of the inlet is A₁ = 10 cm². The cross area of the outlet is A = 50 cm². Determine the following components: (i) The mass flow rate at the outlet me = (ii) The volumetric flow rate at the inlet and outlet, (AV); and (AV)e, respectively. (iii) The velocity of water flow at the inlet and outlet, V₁ and Vė, respectively. (iv) The specific enthalpy change of the control volume: h₂ - h₁. (v) Discuss the possible function of this diffuser. i e

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
