Document Summary
Fe/eit sample examinations: the radius of a hypothetical electron orbit is known to be 0. 75 a. It has a 1 cm2 cross section and a speci c gravity of 0. 6. A one- fth scale model of the venturi meter is built, and water is used as the test uid. Viscosity of the air is 1. 82 10 5 n s/m2. What will be the approximate ratio of the model to the actual velocities observed? (a) 0. 32 (b) 3. 1 (c) 11 (d) 54. 5 m (a) 90 kn (b) 440 kn (c) 880 kn (d) 980 kn: a 150 m long surface vessel is modeled at 1:50. Most nearly, what speed must the model travel if a 40 kph similarity is desired: when a thin-bore, hollow glass tube is inserted into a container of mercury, the surface of the mercury in the tube. = 42 440 106 pa (42. 4 gpa)
