Explain the process of formulation of steam from 0⁰C water with T-H diagram Answer : Consider formation of steam from ice at -100 C i) Solid phase- When the heat is added in ice which is at -100 C the temperature of ice increases to 00 C as shown in figure by process a ... is added up to 1000 C, in this region no phase change takes place, there is only liquid phase present. ...
Represent constant volume process on PV & TS diagram for steam. Answer : Represent constant volume process on PV & TS diagram for steam. ...
In a constant pressure process steam is generated from 10 bar and 0.8 dry condition till it become dry and saturated. Determine amount of heat added per kg of steam. From steam table at 10 bar Tsat = 179.9°C hf = 762.6 kl/kg, hg = 2776.2 kJ/kg Answer : Constant pressure process Final condition of steam is dry saturated Enthalpy of dry steam = hg= hf + hfg =2776.2 KJ/Kg .Given Latent heat of vaporization = hfg = hg - hf =2776.2-762.6 =2013.6 KJ/Kg Initial condition ... hfg = 762.6+0.8 X 2013.6 =2373.48 KJ/Kg Heat added = hg-hw = 402.72 KJ/kg...
Explain Dalton's law in respect to steam condensers. Answer : It states that' The pressure exerted by mixture of air and steam is equal to sum of partial pressures, which each constitute would exert, if it occupies the same volume . Mathematically, Pc ... mixture of air and steam Pa = Partial pressure of air Ps = Partial pressure of steam ...
Explain the phases of formation of steam. Answer : Different phases of Formation of steam Consider formation of steam from ice at -200 C i)Solid phase- When the heat is added in ice which is at -20 0C, the temperature of ice increases ... the temperature of steam which is called as superheating and in this region only vapour is present. ...
