A hypodermic needle is 3.10 cm in length and 0.39 mm in diameter. What pressure difference between the input and output of the needle is required so that the flow rate of water through it will be 1 g/s? (Use 1.0 ✕ 10−3 Pa · s as the viscosity of water.)
Q8. Water is dispensed from a hypodermic needle by pushing the syringe plunger at a constant speed of 20 mm/s. What is the pressure (PA) inside the syringe? (10) 20 mm/s 40 mm 1 mm
15. A hypodermic syringe has a 1.0 cm diameter piston, and is connected to a needle of area 0.071 mm². If the needle were inserted into a blood vessel of maximum interior gauge pressure 80.0 mmHg, how much force (in N, minimum) should be exerted on the piston to allow for injection? 16. Continuing with #15, how much inward force acts on the fluid at the needle? (This just equals the outward force from the blood vessel at the threshold...
A patient is given an injection with a hypodermic needle 3.2 cm long and 0.26 mm in diameter. Part A Assuming the solution being injected has the same density and viscosity as water at 20 ∘C, find the pressure difference needed to inject the solution at the rate of 2.0 g/s .
3. A hypodermic syringe contains a medicine with the density of water. The barrel of the syringe has a cross-sectional area A = 2.50 x 10-5 m, and the needle has a cross- sectional area a = 1.00 x 10- m?. In the absence of a force on the plunger, the pressure everywhere is 1.00 atm. A force of magnitude 2.00 N acts on the plunger, making medicine squirt horizontally from the needle. Determine the speed of the medicine as...
A patient in the hospital is receiving a saline solution through a needle in their arm. The needle is 2.20 cm long, horizontal, with one end in a vein in the arm, and the other end attached to a wide tube that extends down from the bag of solution, which hangs from a pole so that the fluid level is 90.0 cm above the needle. The inner radius of the needle is 0.250 mm. The top of the fluid is...
A syringe has a fine needle with an inside diameter of 100 μm. The barrel has a diameter of 2.35 cm and is filled with water. Calculate the velocity of water as it squirts horizontally from the needle if you apply a force of 1.85 N onto the plunger. (Hint: you may approximate the area of the barrel to be much larger than the area of the needle).
Review Constants Periodic Table Su Previous Answers A syringe is filled with water and fixed at the edge of a table at height h = 1.0 m above the floor (Figure 1). The diameter of the piston is du = 25 mm, the needle has length L = 50.00 mm, and the inner diameter of the needle is de = 1.0 mm. You press on the piston so that it moves at constant speed of 3.00 trim's. Correct Significant Figures...
Saline solution is delivered into a patient’s vein through a needle. The saline solution has a viscosity of 0.37 × 10-3 N s m-2, a density of 1060 kg m-3, and is delivered through a 7 cm long needle with an internal diameter of 0.24 mm directly into the patient’s vein in which the blood pressure is 130 mmHg. The saline solution must be delivered at a flow rate of 0.04 × 10-6 m3s-1. How high must the saline solution...
