Sometimes manometer dimensions have a signifi canteffect. In Fig. containers ( a ) and ( b ) are cylindricaland conditions are such that p a = p b . Derive a formula forthe pressure difference p a - p b when the oil–water interfaceon the right rises a distance ∆ h< h , for ( a ) d << D and ( b ) d=0.15 D .

[Fluid dynamics] a.) For your science exhibit, you want to make a block of wood float at the interface between a layer of oil of unknown density ?_???, and water (?_????? = 1000 [kg/m^3]) inside a container as shown. What must be the density of the oil so that only 30.0% of the wood is submerged in water? b.) Water is flowing through a pipeline shown onthe right. The radii of the pipe at points 1 and 2 are0.500 [m] and 1.50 [m], respectively. The volume flowrate through the pipeline is 2.50 [L/s]. If the pressureat point 1 in the pipe is 200 [kPa], what is the pressureat point 2, located 5.00 [m] above point 1?
If a scuba diver descends too quickly into the sea, the internal pressure on each eardrum remains at atmospheric pressure, while the external pressure increases due to the increased water depth. At sufficient depths, the difference between the external and internal pressures can rupture an eardrum. Eardrums can rupture when the pressure difference is as little as 35 kPa. What is the depth at which this pressure difference could occur? The density of seawater is 1025 kg/m3. 1)sketch (include everything in the system) 2)solution(step by step)
An air-filled, hemispherical shell is attached to the ocean floor at adepth of 10 m as shown in fig. A mercury barometer located inside the shell reads 765 mmHg (absolute pressure inside the shell)m, and a mercury u-tube manometer designedto givethe outside water pressure indicates differential reading of 735 mmHg as illusrated. Based on these data,what is the atmospheric pressure at the ocean surface for seawater (SG=1.03)
Here, a liquid's density is to be determined by a 1-cm diameter cylindrical hydrometer whose division marks are non visable. The hydrometer is first dropped in water, and the water level is marked. The hydrometer is then dropped into the 'liquid x', and it is observed that the mark for water has risen 0.85 cm above the liquid–air interface. In this case, the height of the originalwater mark is 12.7 cm. As such, how would I determine the density of the liquid?
For most gases at standard or near standard conditions, the relationshipamong pressure, density, and temperature is given by the perfect gasequation of state: p = ρRT, where R is the specific gas constant. For airat near standard conditions, R = 287 J/(kg · K) in the International System of Units and R = 1716 ft · lb/(slug · ◦R) in the English Engineering System of Units. Using the above information, consider the following two cases: a. At a given point on the wing of a Boeing 727, the pressure andtemperature of the air are 1.9 × 104 N/m2 and 203 K, respectively.Calculate the density at this point.b. At a point in the test section of a supersonic wind tunnel, the pressureand density of the air are 1058 lb/ft2 and 1.23 × 10−3 slug/ft3,respectively. Calculate the temperature at this point.
A milkshake has fairly similar density to that of water (m s = 1200 kg/m3) but is far more viscous ( = 1kg/ms) (a) Say you try to drink a milkshake through a straw that is 30 cm long and 5 mm in diameter. Your lungs are capable of creating a vacuum pressure of 3000 Pa. (Vacuum pressure just means a pressure below that of the atmosphere, so plung = patm 3000 Pa.) You Önd that if you place the straw just at the surface of the liquid, you are unable to suck the milkshake through the straw, but if you push the straw deeper into the shake, you can. To what depth, d, would you need to push the straw in order to just start to sip the milkshake?(b) Suppose you push the straw to a depth of 10 cm and suck with a suction pressure of 3000 N/m2. What volume áow rate of milkshake can you produce through the straw
