A sight is taken with an Engineer's Level at rod held 200 meters away and an initial reading of 2.3 meters is observed. The bubble is then level through 7 spaces on the level tube, and the rod reading is 1.8 meters. One division in the level tube is equal to 0.6 mm. ASAP PLEASE What is the total distance moved by the bubble in seconds? What is the difference in rod readings in meter

Quiz 1 Q1: A reducing elbow is used to deflect water flow at a rate of 25 kg/s in a horizontal pipe upward by an angle of 45° from the flow direction while accelerating it. The elbow discharges water into the atmosphere. The diameter of pipe is 150 mm at the inlet and 30 mm at the exit. The elevation difference between the centers of the exit and the inlet is 40 cm. The volume of the water in bend is 0.053 m³. Determine the resultant force exerted on bend. 30 mm 150 mm 40 cm 45° Water Q2: Water is siphoned from a large tank and discharges into the atmosphere through a 2-in.- diameter tube as shown in Fig. The end of the tube is 3 ft below the tank bottom, and viscous effects are negligible. (a) Determine the volume flowrate from the tank. (b) Determine the maximum height, H, over which the water can be siphoned without cavitation occurring. Atmospheric pressure is 14.7 psia, and the water vapor pressure is 0.26 psia H 2-in. diameter 10 ft 4 ft D
