Match List-Iwith List-il and select the correct answer using the codes...
List-I consists of different flow measurement devices, while List-II describes the specific applications or characteristics of these devices. We need to match the devices in List-I with their corresponding applications in List-II.
- Orifice meter: Orifice meters are commonly used for measuring the flow rate of fluids in pipes. They work based on the principle of creating a pressure drop across an orifice plate, which is then used to calculate the flow rate. Therefore, the orifice meter is best suited for measuring flow in a pipe of any inclination.
- Broad crested weir: Broad crested weirs are used to measure the flow rate of fluids in open channels. They consist of a flat plate placed across the channel, causing the water to flow over the plate. The flow rate can be determined by measuring the height of the water above the plate. Therefore, the broad crested weir is used for the measurement of flow in a channel.
- Pitot tube: Pitot tubes are commonly used to measure the velocity of fluid flow in a pipe or channel. They work based on the principle of converting the dynamic pressure of the fluid into velocity. By measuring the dynamic pressure using a Pitot tube, the velocity of the fluid can be determined. Therefore, the Pitot tube is best suited for the measurement of velocity in a pipe/channel.
- Rotameter: Rotameters are flow meters that use a tapered tube and a float to measure the flow rate of fluids. The float rises or falls in the tapered tube based on the flow rate, and the position of the float can be used to determine the flow rate. Rotameters are commonly used for measuring upward flow in a vertical pipe.
By matching the devices in List-I with their corresponding applications in List-II, we find that:
A. Orifice meter - 3 (Measurement of flow in a pipe of any inclination)
B. Broad crested weir - 1 (Measurement of flow in a channel)
C. Pitot tube - 2 (Measurement of velocity in a pipe/channel)
D. Rotameter - 4 (Measurement of upward flow in a vertical pipe)
Therefore, the correct answer is option (c) 3 1 2 4.
