Page 3 Ethyl alcohol flows in a pipe at 20°C. The pipe is not open to the atmosphere. The manometer fluid is mercury. Both manometers are open to the atmosphere. Elevations are given in cm. Find the pressure [Pa, gage] and velocity [m/s] at Point 1. 100 68 Assume steady, ideal flow. 58 50 39 Elev in cm NOT TO SCALE
An oil of specific gravity 0.89 is flowing through a horizontal venturimeter fitted to a 242 mm diameter pipe at the rate of 108 liters/s and throat diameter is 98 mm. The entrance and throat of the venturimeter are connected in the two limbs of a U-tube mercury manometer. The difference in mercury level shows 841 mm. Calculate (i) the head difference in m of oil, (ii) the theoretical discharge in m3/s, (iii) the actual discharge in m3/s, and (iv) the coefficient of discharge of a venturimeter. If instead of a U-tube mercury manometer, the pressure gauges are inserted at the entrance and throat of venturimeter. Find (v) the pressure at the throat in N/mm2, if the entrance pressure gauge shows0.13 N/mm2.
