Chapter 3.9, Problem 8P

Interpretation Introduction

Interpretation:

The time taken to filling the pool.

Concept Introduction:

The mass balance equation for the material entering from three sources: hose, barrel, and rain.

$\frac{dM}{dt}={\dot{m}}_{hose}+{\dot{m}}_{barrel}+{\dot{m}}_{rain}$

Here, mass flow rate of hose, barrel, and rain is ${\dot{m}}_{hose},{\dot{m}}_{barrel},\text{and}{\dot{m}}_{rain}$ respectively.
