Chapter 14.1, Problem 7LC

Interpretation Introduction

Interpretation: To explain how a pressurized garden sprayer works.

Concept Introduction: Boyle's law gave the relationship between pressure and volume. According to this law $\text{PV}\text{=}\text{K}$ , where, P is pressure, V is volume and K is a constant.

Explanation of Solution

The best equipment for spraying pesticides on the lawn and yard is a pressure sprayer. A sprayer is perfect for all-year-round landscaping needs, including those involving fertilizer, herbicides, fungicides, and insects.

Bernoulli's theorem is used by the sprayer. The buoyant force a fluid exerts is proportional to the weight of the fluid it has displaced.

A pressure sprayer is a container used to apply liquids under pressure. The container is first filled with compressed air. Cast iron, as well as stainless steel, are commonly used in the design of units.

Pressure is released when liquid is sprayed by the hand as the amount of liquid inside the container is decreased.
