The effective diameter in the formula above is often determined experimentally by sieving the particles through a series of progressively finer sieves and then using the expressions in Chapter 11. Suppose we are fluidizing a bed of crushed sub-bituminous coal with gas. Calculate the minimum fluidization velocity assuming the following properties.

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
