The 10 foot wide circle quarter gate ab is articulated at a. determine the contact force between the gate and the smooth surface at b due to the pressure of the water acting on the gate. use γ = 62.4 lb / ft^3 for the water. r=8 ft

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
