Showering: More Heat with Less Water

Overview

Objectives/Goals My objective is to indentify the key aspects of a showerhead design that transfers the maximum amount of heat to the body using the least amount of water. Methods/Materials The materials used in this project were, funnel, hose, thermometer, plastic bag, fifteen showerheads, and timer. Procedures: 1. Fifteen showerheads were timed to see how long six gallons took to spray. A plastic bag of 90 degrease water was then hung twelve inches away from the shower in a position that the shower hit when running. 2. Each showerhead sprayed out six gallons of water, hitting the bag when running. The shower sprayed water at 110 degreases. 3. After six gallons have been sprayed out, the temperature of the bag was recorded to see how much the temperature of the bag rose. Results Showerheads numbers 2, 6, 7, and 15 had the best GMP per temperature increase. Conclusions/Discussion Based on this experiment, it appears that showerheads that spray droplets of water in random patterns tend to transfer more heat with less water.
