21. Concepts under Fluid Dynamics
22. _______________________ is an idea of fluid dynamics. It says that as speed of the fluid increases, pressure decreases. ... For a steady flow, the amount of fluid entering the pipe must equal the amount leaving the pipe, so the fluid speed in the thin part must increase.
24. If cross-sectional area of pipe decreases, the speed of fluid must increase according to:
25. If radius of droplet becomes half then its terminal velocity will be:
26. As the water falls from tap, its speed increases and cross sectional area:
27. Blood has density equal to that of:
28. When the body reaches its terminal velocity, the acceleration of the body becomes
29. One Torr is expressed in 𝑁𝑚−2 as:
30. The maximum constant velocity of an object falling vertically downward is called:
31. The equation 𝐹 = 6𝜋𝜂𝑟𝑣 is called:
32. An object moving through a fluid experience a retarding force called:
33. Speed of efflux can be determined by applying:
34. A man standing near a fast moving train may fall.
35. Branch of applied science that describes the movement of liquid and gases.
36. It states that, "in the case of steady flow, the amount of fluid flowing past one point must be the same as the amount of fluid flowing past another point, or the mass flow rate is constant."
37. It states that, "as the speed of a fluid increases, there is a simultaneous decrease in the pressure of a fluid and a decrease in it's potential energy.
38. BONUS ROUNDIt is the sub-part of Fluid Mechanics that studies the flow of Fluid
39. Both Laminar flow and Turbulent flow occur inside or outside an object.
40. BONUS ROUNDIt is the branch of science that covers the behavior of fluids in a state of motion or rest.
42. Bernoulli’s equation is obtained by applying law of conservation of.
43. Venturi meter is a device used to measure:
44. The study of properties of fluids in motion is called
45. Abstraction and Decomposition are separate concepts, you would usually choose to do either one or the other
