- B h A The picture shows a section of pipe within a closed system (not open at the ends). Water (density 1000 kg/m³) flows from left to right in the system. At point A, the pipe diameter is 60 cm, the speed of the water is 24 m/s, and the pressure is 1.3 atm. At point B, the pipe diameter is 2.4 m. The height difference h is 3.5m. What is the pressure at point B? (Hint, use continuity to determine the speed at point B, then use the Bernoulli equation.) O1.9 atm 1.3 atm 0.85 atm 3.8 atm 2.9 atmA horizontal water pipe goes from a large diameter to a small diameter and then back to the first diameter as shown in the figure below. The level of water in the small vertical tubes provides us with information about the water pressure in the two different sizes of pipe. The inside diameter of the larger pipe is 2.70 cm and water travels through both sizes of pipe with a volume flow rate of 2.10 x 10-4 m³/s. Determine the inside diameter of the smaller pipe. m 8.00 cm * 4.00 cmA pressurized tank supplies water to a hose. The hose rises h=1.3 m above the tank before spraying water a speed of 6.0 m/s. What is the pressure in the tank? (Patm= 1.013x105)
- The gage pressure of the air in the tank shown in Figure 1 is measured to be 750KP.. Determine the differential height h of the mercury column.9. A fountain shoots water 8 m straight up. a. What is the pressure at the point where the water exits the pipe at ground level and when it reaches it maximum height of 8 m? b. How fast must the water be moving when it exits the pipe at ground level?In order to take a nice relaxing bath after this final, you fill up a bathtub with warm water. To fill the tub, water travels at 9 m/s in a pipe under your house. The faucet (where the water exits into the tub) in your house has a diameter twice that of the pipe under your house. The water pressure in the pipe/faucet is the same everywhere. (a) What is the height of your faucet, relative to the pipe under your house? (b) Let's do some special cases sensemaking! If the diameter of the faucet were the same as the diameter of the pipe under your house and the pressure was the same everywhere, what would the height differ ence need to be? explain.
- 9A 5.8 cm diameter horizontal pipe gradually narrows to 4.1 cm. When water flows through this pipe at a certain rate, the gauge pressure in these two sections is 31.0 kPa and 22.2 kPa, respectively. Part A What is the volume rate of flow?Suppose you have a 9.6 cm diameter fire hose with a 2.2 cm diameter nozzle. a.) Calculate the pressure drop due to the Bernoulli effect as water enters the nozzle from the hose at the rate of 40.0 L/s. Take 1.00 × 103 kg/m3 for the density of the water. b.) To what maximum height, in meters, above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.)

If the water is flowing with a speed of 1.25[m/s] at point A, what is the pressure difference between points A and B? 1.00 cm Select one: A 2.34[kPa] ○ 2.50[kPa] O 0.781[kPa] O 1.88[kPa] 0.500 cm BA horizontal pipe carries a smoothly flowing liquid of density of 1290 kg/m³. At Locations 1 and 2 along the pipe, the diameters are dj = 6.79 cm and d2 = 2.79 cm, respectively. Is the flow speed at Location 2 higher or lower than the flow speed at Location 1? d Location 1 Location 2 d2 O higher cannot tell from the data lower The flow speed at Location 1 is 1.87 m/s. What is the pressure difference AP between Location 2 and Location 1 (including its sign)? Ignore viscosity. AP = РаThe container shown is filled with mercury. It is open to atmosphere on the left and closed on the right. What is the pressure at point B, in kPa (kiloPascal)? Pmercury 13,600 kg/m³,1.00 atm = 1.00 x 105 Pa = 100 kPa, and g = 10.0 m/s². Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive.
