1.An ungated spillway is to deliver 150,000 cfs with a crestelevation of 1000 ft. The upstream reservoir elevation is not toexceed the elevation of 1030 ft. The streambed is at elevation 800ft. Determine the length of the crest required.
2.A rigid tank contains 5 lbm of water at 60 psia, 320 F. Thetempertaure of the water drops to 260 F as a result of heattransfer to the surroundings Determine:
a. The final pressure in tank
b The mass of the liquid water and vapor water at the finalstate
c Show this process on a p-v diagram w/ respect tothe saturation/actual pressure values etc.
d. The heat transfer
