Mean and RMS values for given discrete data.

Question

3. The shaft below is made of steel (G = 80GPa). It has a diameter of 25mm and is fixed and supported at the two ends of the shaft, A and D. (i) Is this a statically indeterminate problem? Why? (ii) Can you draw the torque load diagram without first resolving the reaction torques at A or D? (iii) Determine the reaction torque at A and D. (iv) Draw the torque load diagram. (v) Determine the angle of twist at section AB. B 90 N·m 0.6 m 0.75 m 0.9 m 90 N-m

3- A horizontal Venturi meter with d1 = 20 cm, and d₂ = 10 cm, is used to measure the flow rate of oil of sp.gr. 0.8, the discharge through venture meter is 60 lit/s. find the reading of (oil-Hg) differential Take Cd = 0.98.

4- A horizontal Venturi meter is used to measure the flow rate of water through the piping system of 20 cm I.D, where the diameter of throat in the meter is d₂ = 10 cm. The pressure at inlet is 17.658 N/cm2 gauge and the vacuum pressure of 35 cm Hg at throat. Find the discharge of water. Take Cd 0.98.
