Example 1: Material Balances on Distillation ColumnA liquid mixture of benzene (B) and toluene (T) containing 55% B by mass is fed continuously to a distillation column with a feed rate of 100 kg/h. A product stream leaving the top of the column (overhead product) contains 85% B and a bottom product stream contains 10.6% B by mass. Determine the mass flow rate of the overhead product stream and the mass flow rate of the bottom product strea​

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
