The discharge from the renenutet sugar beet plant causes the do at the critical point to fall to 4.0 mg · l−1. the meskhenet stream has a negligible bod and the initial deficit after the river and wastewater have mixed is zero. what do will result if the concentration of the waste (lw) is reduced by 50%? assume that the flows remain the same and that the saturation value of do is 10.83 mg · l−1 in both cases.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

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
