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.

FLUID MECH Support your answer with the appropriate solution and diagram. 4. The water level in a tank is 20 m above the ground. A hose is connected to the bottom of the tank, and the nozzle at the end of the hose is pointed straight up. The tank is at sea level, and the water surface is open to the atmosphere. In the line leading from the tank to the nozzle is a pump, which increases the pressure of water. if the water jet rises to a height of 27 m from the ground, determine the minimum pressure rise in kPa supplied by the pump to the water line.

1. Estimate the volume flow rate and mass flow rate of water flowing in a river whose channel is roughly rectangular with a depth of 0.6 m and a width of 4 m, and which has a flow speed of 0.85 m/s. A weir on the river provides a working head of 1.4 m for a turbine/generator. If one third of the river flow could be diverted through the turbine which has an efficiency of 75%, estimate the electrical power that could be generated.

Example 6.2 [Fishbowl Practice] A typical capillary viscometer (a device for measuring viscosity) has the flow diagram shown in Fig. 6.7. It consists of a large-diameter reservoir and a long, small diameter, vertical tube. The sample is placed in the reservoir, and the flow rate due to gravity is measured. The tube is 0.1 m long and has a 1 mm ID. The height of the fluid in the reservoir above the inlet to the tube is 0.02 m. The fluid being tested has a density of 1050 kg/m³. The flow rate is 108 m³/s. What is the viscosity of the fluid? h Ok 7 The Momentum b Ch 8 One Dimension P2-0 psig Course Revine
