Pressure in Liquids/Blood Pressure

PHY 100 & 103

The objective is to see and measure the effect by which liquid pressure varies with depth via blood pressure measurements taken at different heights of the wrist. A small wrist cuff device is used. Unit conversion from Pascals to mm of mercury will be practiced and needed to verify agreement with the theory that a change in liquid pressure equals the product of liquid density times gravity times the change in depth.

Equipment

Notes

A barometer and a thermometer are already present in each room. Make sure that the room has plenty of paper.

Along with the initial apparatus set-up, supply a sufficient number of the appropriate paper procedure handouts for all of the lab sections that will use the set-up over the course of the week. Print the PDF, duplicate to double-sided pages, staple, and leave pile on instructor's table prior to first use of set-up.
