Calculate the production rate of dried milk and the volumetric flow rate.
00:06
We need to first find the mass flow rate of milk.
00:12
Of milk, that's the mass flow rate of our dry divided by 0 .30.
00:18
So we plug in 9 .6 over 0 .30 to get 32 kilograms per minute.
00:26
Then the mass of the water that's evaporated is just the mass of the milk minus the mass of the dry.
00:35
And so we get 22 .4 kilograms per minute.
00:40
Now we need to determine our volumetric flow rate.
00:45
We first need to find our number of moles of h2o, which is our 22 ,400 grams per minute, over 18 .01 grams per mole, to give us 1244 moles per minute.
01:03
Now what about the total moles of outlet gas? for outlet gas, that's our 1244 moles per minute divided by .12, which is 10366 .6 .moles per minute.
01:22
We also need to find our moles of dry air, which is 88 % of our 10366 .6.
01:35
Which is 9122 .6 moles per minute.
01:41
Now we could find our v -inlet...
