Question

An orifice meter with an orifice diameter of 15 cm is inserted in a pipe with a diameter of 30 cm. The pressure difference measured by a mercury oil differential manometer on the two sides of the orifice meter gives a reading of (x = 50 cm) of mercury. Given the specific gravity of the oil (Soil = 0.9) and the coefficient of discharge of the meter is 0.64, calculate: i. pipe area (A1) ii. orifice area (A2) iii. area ratio (m*) iv. difference of pressure head (h) v. entrance velocity (v1) vi. theoretical flow rate (Q1) vii. actual flow rate (QActual)

Step 1

- The diameter of the pipe (D1) is 30 cm. - The area of the pipe (A1) can be calculated using the formula for the area of a circle: \( A1 = \pi \left(\frac{D1}{2}\right)^2 \). \[ A1 = \pi \left(\frac{30 \text{ cm}}{2}\right)^2 \] \[ A1 = \pi \left(15 \text{ Show more…
