# Investigating the Influence of a Ship's Bow on Water Resistance

Medium
We're going to investigate how the shape of a boat's bow affects the amount of water resistance it experiences. We'll use a water tank, pumps, and three different wooden boats to measure the amount of drag.

## Hypothesis

The hypothesis is that the boat with a V-shaped bow and a curved bottom will experience the least amount of fluid resistance.

## Method & Materials

You will arrange two water tanks, place three water pumps outside the tank, and fix the three wooden boats into the inner tank. You will also place a 300-gram weight inside the wooden boat to stabilize it.
You will need a water tank measuring 1.0m x 0.8m x 0.8m (inner tank), a water tank measuring 1.5m x 1.0m x 0.3m (outer tank), three water pumps, a wooden boat - cuboid shape, a wooden boat - half cylindrical in shape, a wooden boat – curved bottom with a V-shape bow, a Newton spring balance, a 300-gram weight, a ruler, and two tanks of tap water.

## Results

The results showed that the boat with the V-shaped bow and the curved bottom had the least amount of fluid resistance in water. The cuboid shaped boat had the most fluid resistance.

## Why do this project?

This science project is interesting because it explores the mechanics of a ship and how the shape of its bow affects the amount of water resistance it experiences.

## Also Consider

Experiment variations include varying the number of water pumps to simulate varying flow rates, and repeating the experiment using different weights placed in the boat.
