S) suppose we are given a sequence s of n elements, each of which is colored blue or gold. assuming s is represented as an array, give an algorithm for ordering s so that all the blue elements are listed before all the red elements. you may allocate o(1) additional space for doing so. your running time must be o(n) for full credit.

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

During a steady flow process, the change of energy with respect to time is zero. 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
