Question

In the textbook (Fundamentals of Modern Manufacturing Materials, Processes,and Systems 7th Edition by Mikell P. Groover) chapter 4 problem 8, I’m having trouble trying to understand and solve the problem with the information given to me. Image below.

4.8 (USCS units) A cast iron grade has a melting point of
2156°F. Its specific heat = 0.11 Btu/lbm°F, and its heat of
fusion = 54.2 Btu/lbm. A 200-lbm block of this cast iron
is to be melted. Determine how much heat is required to
raise its temperature from 75°F to its melting point and
olid t
transform it from the solid to liquid phase.

Expert Solution

Step 1

$Given T_{m} = 2156^{o} F C = 0.11 Btu / {lbm}^{o} F LHF = 54.2 Btu / lbm mass, m = 200 lbm T_{1} = 75^{o} F Solid to liquid phase$
