Acetylene (c2h2) is burned with the stoichiometric amount of air during a combustion process. assuming complete combustion, determine (a) the air-fuel ratio on a mass basis and (b) the air-fuel ratio on a mole basis. (c)what would the air to fuel ratio be if propene (c3h6) were burned instead of acetylene?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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
