A cyclone has an outside diameter of 1 m and a rectangular inlet (Height = 0.4 m and Width = 0.2 m). The gas flow rate is 2.4 m3/s (85 ft3/s) carrying particles with a density of 2,000 kg/m3. (a) Demonstrate the gas flow velocity inside the cyclone is equal to 30 m/s; (b) Determine the cut diameter with N = 5 and viscosity of air = 1.8 ´ 10-5 kg/m•s; (c) Estimate its removal efficiency for particles with diameter = 3μ

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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
