What is the accumulation in the system after 4 second if the out flow

1.	What is the accumulation in the system after 4 second if the out flow and in flow rates are 3 g/s and 8 g/s?(a) 12 g(b) 20 g(c) 32 g(d) 40 gThe question was asked in unit test.This interesting question is from Open and Closed Systems in division Introduction to Material Balances of Basic Chemical Engineering
Answer» Correct choice is (B) 20 G Explanation: Accumulation = 4*(8 – 3) = 20 g.
