MAT1322-3X Solution to Final Examination Summer 2017 5 Find the total force, in Newtons, acting on this surface. (Use g= 9.81 m /sec2).
3.(4 marks) Air with 0.05% carbon dioxide flows into a room with volume 200 m3at a rate 2 m3/ min and well mixed air flows out at the same rate. Let Q(t) be the amount of carbon dioxide, in m3, in the room at time t(a) (2 marks) Construct a differential equation that is satisfied by the function Q(t(b) (2 marks) Assume, at time t= 0, the air in the room contains 0.2% carbon dioxide. Solve this initial-value problem to find the function Q(t). . ).
