Fluid Dynamics

The study of the flow of gases and liquids, usually in and around solid surfaces, is known as fluid dynamics in physics and engineering. Fluid dynamics, for example, can be used to evaluate the movement of air through an airplane wing or the surface of a vehicle. It can also be used in ship design to increase the speed at which ships pass through water.

1. Consider the following diagram. The fluid flowing in the pipe is oil (SG = 0.830). The fluid in the manometer is water (SG = 1.00). Water, pw = 1000 kg/m³ 7 cm Oil, p = 830 kg/m³ a. Determine P₂ - P₁ in kPa. b. Determine the direction of flow. (Left to right, or right to left). Explain why this is the case. c. The height of oil between the manometer and the pipe is unknown. Explain how you can still solve the problem without knowing this height. Would this height ever matter? Hint: consider practical issues of design. Could the height be 0 cm? Could it be 1000 cm?
