Problem 3: IV Tube I Doctors use IV drips to deliver saline fluid (s = 1.2) into the vein of patients (hence IV for intravenous). Assume the gage pressure head is 0.00 m at the top of the saline bag and 0.05 m in the vein. The saline fluid has kinematic viscosity v = 1×106 m²/s. The tube is 1.8 m long and has inner diameter of 1.2 mm. If the required flow is 1000 mL/hr, what is the required height from the top of the saline bag to the patient's vein?

Question
Transcribed Image Text:**Problem 3: IV Tube I**
Doctors use IV drips to deliver saline fluid (\(s = 1.2\)) into the vein of patients (hence IV for intravenous). Assume the gage pressure head is 0.00 m at the top of the saline bag and 0.05 m in the vein. The saline fluid has kinematic viscosity \(\nu = 1 \times 10^{-6}\) m²/s. The tube is 1.8 m long and has an inner diameter of 1.2 mm. If the required flow is 1000 mL/hr, what is the required height from the top of the saline bag to the patient's vein?
**Explanation:**
The problem is centered on calculating the necessary height for an IV bag to ensure a specified flow rate of saline into a patient’s vein. Important parameters include the specific gravity, the gage pressure at different points, the kinematic viscosity of the fluid, and the dimensions of the IV tube. The drawing depicts a patient receiving an IV drip, giving a visual context to the setup described in the problem. The objective involves applying principles of fluid dynamics to find the height difference necessary to achieve the desired flow rate.
