 |  Flow Through Pipes 30 Flashcards |  Start |
 | In a pipe network, if the friction factor is the same for all pipes, which statement is true regarding flow rates at junctions? |  Card: 1 / 30 |
| The flow rates at junctions must satisfy the continuity equation, meaning the total inflow equals total outflow. | Card: 2 / 30 |
| Fill in the blank: The ______ is defined as the ratio of the actual velocity of jet of liquid at vena contracta to the theoretical velocity of jet. | Card: 3 / 30 |
| Coefficient of velocity (Cv) | Card: 4 / 30 |
| True or False: The flow rate through a venturimeter is equal to the theoretical discharge multiplied by the coefficient of discharge. | Card: 5 / 30 |
| True. | Card: 6 / 30 |
| Riddle: I change shape as I flow, but my total volume stays the same. What am I? | Card: 7 / 30 |
| Fluid | Card: 8 / 30 |
| What is the relationship between velocity and pressure in a venturimeter? | Card: 9 / 30 |
| As the velocity increases, the pressure decreases according to Bernoulli's principle. | Card: 10 / 30 |
| Which of the following statements about the coefficient of discharge (Cd) is correct? A) Cd is always greater than 1 B) Cd varies from 0.61 to 0.98 C) Cd is constant for all flow conditions D) Cd is independent of fluid properties | Card: 11 / 30 |
| B) Cd varies from 0.61 to 0.98 | Card: 12 / 30 |
| Fill in the blank: The loss of head due to friction in a pipe is given by ______. | Card: 13 / 30 |
| Darcy-Weisbach equation | Card: 14 / 30 |

| False. The maximum power transmission efficiency is 67%. | Card: 16 / 30 |
| What does the term 'equivalent length' refer to in the context of pipe fittings? | Card: 17 / 30 |
| It is the length of an unobstructed straight pipe that would produce the same loss of head as the fitting. | Card: 18 / 30 |
| Riddle: I’m a measure of resistance in flow, related to roughness and flow's speed, what am I? | Card: 19 / 30 |
| Friction factor (f) | Card: 20 / 30 |
| In a flow through a pipe, if the diameter increases suddenly, what happens to the velocity and pressure? | Card: 21 / 30 |
| Velocity decreases and pressure increases due to conservation of energy. | Card: 22 / 30 |
| Fill in the blank: The pressure difference in a manometer indicates the ______ in the pipe. | Card: 23 / 30 |
| Pressure drop | Card: 24 / 30 |
| True or False: The hydraulic radius for a circular pipe is simply the radius of the pipe. | Card: 25 / 30 |
| False. The hydraulic radius is defined as the cross-sectional area divided by the wetted perimeter. | Card: 26 / 30 |
| Which equation is used to calculate the discharge through an orifice meter? | Card: 27 / 30 |
| Q = Cd * A * sqrt(2gH), where H is the head and A is the area of the orifice. | Card: 28 / 30 |
| Riddle: I measure flow with a contraction in my path, my readings depend on pressure’s aftermath. What am I? | Card: 29 / 30 |
| Venturimeter | Card: 30 / 30 |
