2-lbm of water at 500 psia initially fill the 1.5-ft3 left chamber of a partitioned system. the right chamber’s volume is also 1.5 ft3, and it is initially evacuated. the partition is now ruptured, and heat is transferred to the water until its temperature is 300°f. determine the final pressure of water, in psia, and the total internal energy, in btu, at the final state.

a) pressure = 66.985 psia

b) internal energy 920.56  Btu

Explanation:

Given data:

left chamber characterisitics

2lbm water, 500 psia, 1.5 ft^3

right chamber

volume = 1.5 ft^3

when partitioned ruptured, the final volume will be

specific volume will be  

at , From saturated water tables

the final pressure at temperature 300 F

internal energy at fnal stage

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
