GR Generation ratc 18. What assumptions are necessary to solve question 19? A Accumulation rate 0 and Output rate 0 B. Accumulation rate 0 and Generation rate 0 C. Output rate - 0 and Generation rate 0 D. Accumulation rate-0, Generation rate-: 0 and Output rate= 0 19. How long does it take to fill the tank? A. 3.20 hours B. 2.94 hours 346 hours D)2.81 hours 20. A separating process at a recycling facility is separating the glass from the plastic Refer to the table below for the following two questions: Unit weight Feed stream Product stream Prod

Explanation / Answer

General mass balance equation

Input rate - output rate + generation rate = Accumulation rate

If the tank is continously filled with no output and no reaction is taking place inside the tank

Output rate = 0

Generation rate = 0

Mass balance equation becomes

Input rate = Accumulation rate

Accumulation rate tells about the change of rate with respect to time

With the help of Accumulation rate, time will be calculated.

Option C is the correct answer
