The benzoyl peroxide initiated polymerization of a monomer follows the simplest kinetic scheme, that is, Rp = kp[M]( f kd[I]/kt ) 1/2 with all rate constants and f being independent of conversion. For a polymerization system with [M]O = 2 M and [I]O = 10-2 molar, the limiting conversion p∞ is 10%. To increase p∞ to 20%:

What precautions should you take to prevent injuries when dealing with heavy loads?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

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
