Chapter 6.3, Problem 32PPS

To determine

The order of the following groups of rate from least to greatest.

(i) 100 oz/min (ii) 2500 gram/min (iii) 10 lb/min

Answer to Problem 32PPS

Order of rates from least to greatest is: 2500 gram/min, 100 oz/min, 10 lb/min

Explanation of Solution

Given information: 

Given rates are: (i)100 oz/min (ii) 2500 gram/min (iii) 10 lb/min

Formula used:

First, all the different units given will be converted in oz (ounce) only, using following conversion formulae:

(i) 1 Gram $=0.03527$ ounce (ii) 1 lb(pound) $=16$ ounce (oz)

Calculation:

Using above conversion formulae,

2500 gram $=2500\times 0.03527=88.175$ oz

And 10 lb $=10\times 6=160\text{ oz}$

So, all given rates in same units are,

(i) 100 oz/min (ii) 88.175 oz/min (iii) 160 oz/min

Hence, all given rates from least to greatest is ordered as:

88.175 oz/min, 100 oz/min, 160 oz/min or 2500 gram/min 100 oz/min, 10 lb/min
