In an experimental study, peach purée is being concentrated in a continuous vacuum evaporator at a rate of 65 kg/hr. the feed material has a temperature of 15℃ and a total solids content of 10.9%. a product of 40.1% total solids is withdrawn at a temperature of 40℃, and condensate leaves the condenser at 35℃.
a) calculate the flow rate of the product and condensate streams.
b) if steam condensing 120℃ is used to supply the heat of evaporation, calculate the steam consumption in kg/hr. the specific heat of the solid material is 2.09 kj/kg. k.
c) cooling water enters the condenser at 20℃ and leaves at 30℃. calculate the cooling water flow rate.

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
