shown. 3.b. Bring the meter down to the vessel's lower surface and record P = kPa (4 sig figs). 3.c. Depth calculation, P = Potpgh, h = m (4 sig figs). Here Po and P must be in Pa, not kPa. Bring the meter back up to the upper surface of the right container. Pick up the 500 kg mass, and drop it in the "water column on the left". Watch and it will "bob up and down" a bit as it settles. The water level has risen, and you can see this with the meter's tip on the right, it's just under the surface. 4.a. Bring the meter up to the water's surface (as shown, barely touching it). Record the pressure P = 101.3__kPa (6 sig figs). This should read as is shown. 4.b. Bring the meter down to the vessel's lower surface and record P = kPa (4 sig figs). 4.c. Depth calculation, P = Pc +pgh, h= m (4 sig figs). Here Pc and P must be in Pa, not kPa. 4.d. The upper surface of the 500 kg mass on the left, closely matches the height of the water's surface on the right. Does this imply that the object on the left has its upper surface at water level, that it is barely 100% submerged? Yes/No. If so, then "f the fraction submerged, is f= 1.0. Given that f = Pobj Pliq' does this imply that the object on the left has the same density as water (being barely 100% submerged)? Yes/No. 4.e. If the object had been lowered into the water with a cable, before entering the water, calculate T, =_ N. 4.f. If its density is the same as water, and its mass is as well, calculate B = Mliq g = N. Then, T2 = _ N. Go to the next page Click on the Flow tab (upper left). Click on Ruler (upper right). A, V1 = A2 V2 P,tpgh, +1/2 pv, = P2+ pg h2 + 1/2 p V 2 Conversions to metric: L/s needs to be m'/s, so + by 1000, and kPa needs to be Pa, so x by 1000. Measurements using the ruler, and Speed and Pressure meters, are very critical. Please do the "best you can" per the figures. 5.a. figure 5.b. figure 1.6 m's 5.a. Measure the pipe's inside diameter with the ruler as is shown, getting 2.0 m. Then r, = m. Pull the Speed meter into the flow, which is water, and v, = m/s. 5.b. Critical setup: pull the right-hand 3 handles down as is shown, with the middle one at 1.0 m diameter. The flow speed v, is 1.6 m/s to the left, measure it just downstream of the ruler, v2 = m/s. Using "A = n r2", calculate it from A, V, = A2 V2, V2 = m/s Do measured and calculated speeds verify one another? Yes/No. 5.c. Height and pressure measurements, where r, = 1.0 m. Place the ruler as shown. It is measuring "h," in the pipe. Each tic mark is .2 m. Three tic marks up is h, = _ m. Place the lower tip of the Pressure meter at this height, as is shown. Measure the pressure here in Pa, P = Pa (6 sig figs, convert from kPa). 5.d. Height and pressure measurements. where r. = 0.5 m
