Using the Steam Tables, determine the heat absorbed by the boiler (KW) and Wsf when subcooled water at pressure = 5 Mpaa (subcooled by 64 deg C measured at the boiler inlet), is superheated to 100 degrees SH at the same pressure. Flow rate is at 10 cubic meters per minute. Ans.: a) Qa =. boiler inlet to convert to mass flow rate. Process is isobaric (Constant Pressure, where Q =AH). _b)Wsf= _Hint: Use v at compressed water temp. at 2. Use only the MD below to solve this Item. Use it by plotting data and process to determine items being asked. Steam entersa turbine at 3.0 MPaa and 700 deg. C, and expands isentropically to 0.098325 MPavac. For 4.2| steam undergoing an irreversible adiabatic process under the same properties, what is (a) the actual work done (KJ) if AKE = 0 and h2' = 2,400 KJ/kg, Ans: the following: actual quality at exhaust. Ans: (b) Determine _c) Ideal turbine work. Ans: _d) Ideal steam temp at the f) actual entropy at steam outlet. _h) irreversible adiabatic expansion efficiency. exhaust. Ans. e) Degree Superheat of the steam at turbine inlet. Ans g) Actual temp. of steam at the exhaust. Ans. i) AS for irreversible adiabatic process Ans Ans.
