PS: E=LxC(t2-t1)x12

is this the correct formula?,if so how do i find

length of rod??

Q: given the following saturated press. conditions,if the steam drum water level were to swell 6.35cm above the NOWL,determine the mass of water that moved within the steam drum.(operating press. 31,026mm Hg,steam drum is 9.754m long,1.22m diameter)
