A steady laminar flow is taking place between two parallel plates. The distance between the plates is 2 mm. Coefficient of dynamic ƏP = -10 kN/m³ is observed in the flow. The average velocity of flow is dx viscosity is 5 x 10-2 kg/ms and pressure gradient, (in mm/s,round off to next higher integer).

Highway Drainage

Highway drainage is the process of extracting and regulating the excess surface water on the pavement by giving the desired slope. The construction of a highway drain helps to divert the water present on the surface, and sub-grade by the means of slope. Highway drainage systems are a necessary part of smooth functioning of traffic, since the highway drainage systems provide proper disposal of unwanted substances from the highways.
