Athree effect evaporator is run in parallel mode. this is, fresh feed which 10% nonvolatile solid is fed in at 120 of to each effect. product streams from all effects are 60%. assume that is no bpr and that there is a 40 of temperature driving-force difference in each heat exchanger. condensate temperature in the final effect is 120 of. assuming that heat capacities are constant at 1 btu/lb of and that latent heat of vaporization of water is 1,000 btu/lb. calculate the feed rate to each state if 10,000 lb/hr of saturated stem is used in the first stage.

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
