Hot exhaust gases leaving an internal combustion engine at 400 C and 150kPa at a rate of 0.8 kg/s is to be used to produce saturated steam at 200 C in an insulated heat exchanger. Water enters the heat exchanger at the ambient temperature of 20 C, and the exhaust gases leave the heat exchanger at 30 C.

The hammer throw is a track-and-field event in which a 7.30-kg ball (the hammer) is whirled around in a circle several times and released. It then moves upward on the familiar curved path of projectile motion and eventually returns to the ground some distance away.

In 1985, General Motors was evaluating the acquisition of Hughes Aircraft Corporation, and assumed that Hughes was of approximately the same risk as Lockheed and Northrop. Given the following information in the table, and also assuming that cash flows are perpetual, compute the value of Hughes using the WACC approach
