The maximum work output from two finite bodies-one at temperature T1 and the other at temperature T2 is

A. \(W_{max} = C_p \left( \sqrt {T_1} - \sqrt {T_2} \right)^2\)
B. \(W_{max} = C_p \left( \sqrt {T_1} + \sqrt {T_2} \right)^2\)
C. \(W_{max} = C_p \left( \sqrt {T_1} \sqrt {T_2} \right)^{1/2}\)
D. \(W_{max} = \frac 1 2 C_p \left( \sqrt {T_1} - \sqrt {T_2} \right)^2\)
Answer» B. \(W_{max} = C_p \left( \sqrt {T_1} + \sqrt {T_2} \right)^2\)
