Transcribed Image Text:Seat No.
Section:
1. Using the Steam Tables, find and entropy of steam at the inlet and outlet of a boiler and heat added when subcooled water at
solutions in separate sheets as required. Indicate all of your answers on this page in the provided blank lines.
pressure = 5 Mpaa (subcooled by 64 deg C measured at boiler inlet), is superheated to 100 deg C SH at the same pressure. Total flow
volume rate of steam = 0.5 cu.m per sec. Indicate units.
a. s1 (boiler inlet)
C. Q =
b. s2 (boiler outlet)
2. Use only the MD below to solve this Item 2 (not ST). Use it by plotting data and process to determine items being asked. Steam enters
a turbine at 90,007.40mmHgabs and 932 deg. F, and expands isentropically to 147.2825 in Hggage. Barometer reading at the power plant =
29.89 inHg. Hint: Use local barometer reading to convert gage to absolute pressures. Use significant figures to work on decimal places for
your answers (answers should be based on the most number of decimal places used in calculation). For 2.5 kg/sec of steam, find (a) ideal
work done (KW) if AKE=0 and actual exhaust enthalpy is 2700 KJ/kg. Ans:
% Determine the following: (c)
(b)ne =
ideal steam moisture at exhaust. Ans:
process. Ans:
e) AS on the actual
(d) Deg. SH of steam at turbine inlet. Ans_
g) actual turbine work Ans:_
f) Actual T at exhaust_
KW
