Question

5. 5.25 Kg/s of oil with a relative density of 0.812 and a pressure of 311 kPa enters a short
pipeline having an inlet diameter that is 1.5 times greater than outlet diameter. At the outlet
the pressure is 295 kPa and is 2.25 m below the inlet. Neglecting friction and viscosity effects
find the diameters of the inlet and outlet; and the velocities of the inlet and outlet pipes.

An intravenous (IV) system is supplying saline solution to a patient at the rate of 0.120 ml/sec through a needle whose radius is 0.150 mm and length is 2.50 cm. The pressure of the blood in the patient’s vein is 8.00 mm Hg. What pressure is needed at the entrance of the needle to cause this flow, assuming the viscosity of the saline solution is (1.00×10⁻³ N ⋅ s/m²)?
PROBLEM 3: The two-fluid U-tube manometer is being used to measure the difference in pressure at two points in a line containing air at 1 atm absolute pressure. The lighter fluid is a hydrocarbon with density equals to 812kg/m³ and the heavier water with density equals to 998kg/m³. The inside diameters of the U tube and reservoir are 3.2 mm and 54.2 mm, respectively. The reading of the manometer is 120.0 mm. Use the formula Pa – P, = R(pa – P6)g - where a and b are the two different fluids and R is the manometer reading. Calculate the pressure drop in (a) mmHg and (b) Pa.

It is a fact that blood flows more rapidly in the aorta than in the capillaries. The cross sectional area of the aorta must be ___________ the total cross sectional area of the capillaries. less than equal to greater than Consider an incompressible liquid flowing in a pipe of constant diameter. ΔP is the pressure difference between the 2 ends of the pipe. Choose the correct statement regarding the volumetric flow. It will decrease with increased ΔP, and increase with greater pipe radius. It will increase with increased ΔP, and increase with greater length of the pipe. it will decrease with greater length of the pipe, and increase with greater pipe radius. it will decrease with increased viscosity of the liquid, and decrease with greater pipe radius.
A popular pool toy allows the user to push a plunger to compress water in a barrel with a diameter of 3.5 cm. The water is compressed with a speed of 1.9 m/s and emerges from a small opening with a speed of 12 m/s. What is the diameter (in mm) of the opening? Assume the toy is oriented horizontally. mm
Suppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.525 m below the heart. For this problem, assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large). The density of blood is 1.05×103 kg/m3 a. Calculate the systolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the top (and greater) number is the systolic pressure. b. Calculate the diastolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the bottom (smaller) number is the diastolic pressure.
A pipe with a radius of 51 cm has water flowing at 5.3 m/s. If water goes into a new pipe with radius 21 cm, how much will the pressure decrease? ΔΡ- unit Pa
When a person inhales, air moves down the bronchus (windpipe) at 13.8 cm/s. The average flow speed of the air doubles through a constriction in the bronchus. Assuming incompressible flow, determine the pressure drop in the constriction. Neglect the change of pressure due to change in height ?y in the wind pipe. If the pressure goes down then the pressure drop is negative. Use 1.20 kg/m33 for the density of air.
In an industrial cooling process, water is circulated through a system. If water is pumped with a speed of 5.20 m/s under a pressure of 5.00*10^5 Pa from the first floor through a 3.80-cm diameter pipe, what will be the pressure on the next floor 3.50 m above in a pipe with a diameter of 3.00 cm?
