Three piezometers located 1000 m apart bottom in the same horizontal aquifer. Piezometer A is due south of piezometer B, and piezometer C is to the east of the line AB. The surface elevations of A, B, and C are 95 m, 110 m, and 135 m respectively. The depth of water in A is 5 m, in B is 30 m, and in C is 35 m. Determine the direction of groundwater flow through the triangle ABC and calculate the hydraulic gradient.

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

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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
