Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

A water truck drives slowly around a construction site, spraying water to keep dust down. A pump maintains a constant pressure of 100 kPa, gage, and the water is dispersed through 20 spray nozzles, each of diameter 1 cm. If the truck is initially filled with 4000 L of water, and the flow rate is constant, determine how long the truck can drive before a refill is needed. [57.0 s]
