Chapter 21: Q. 12 (page 594)

A gas following the $p V$ trajectory of FIGURE $E X 21 . 12$ does $60 J$ of work per cycle. What is $p_{max}$ ?

Short Answer

Expert verified

The value of $p_{max} = 300 k P a$ .

Step by step solution

Step: 1 Definition of pmax:

In case of varying pressure and volume , work done by a gas can be calculated by calculating the area of P-V curve . In case of triangle area of triangle can be calculated by the following formula .

$A = \frac{1}{2} 脳 b 脳 h$

A is area , b is length of base and h is height of triangle.

Step: 2 Finding the value of pmax:

The area enclosed by the graph is equal to the work done by the gas. That example, if we allow the maximum pressure value to be in $k P a$ , as the figure is a triangle, we have

$W_{o u t} = \frac{(p_{max} 鈭� 100) 鈰� 10^{3} 鈰� (800 鈭� 200) 鈰� 10^{鈭� 6}}{2}$

$p_{max} 鈭� 100 = \frac{2 W_{out}}{6 鈰� 10^{鈭� 1}} 鈬� p_{max} = \frac{2 W_{out}}{6 鈰� 10^{鈭� 1}} + 100 kPa .$

Step: 3 Calculation:

We can substitute the value and calculate as follows.

$p_{max} = \frac{2 脳 60}{0.6} + 100 p_{max} = 300 kPa .$
