Chapter 2, Problem 10PP

The dew point temperature T_d can be calculated (approximately) from the relative humidity RH and the actual temperature T by

$\begin{array}{l}{T}_d=\frac{b\cdot f\left(T,\text{}RH\right)}{a-f\left(T,\text{}RH\right)}\\ f\left(T,\text{}RH\right)=\frac{a\cdot T}{b+T}+\ln \left(RH\right)\end{array}$

where a = 17.27 and b = 237.7° C.

Write a program that reads the relative humidity (between 0 and 1) and the temperature (in degrees C) and prints the dew point value. Use the Java method Math.log to compute the natural logarithm.
