Problem 1: You are designing a hydraulic press with a heated copper press plate. The press plate is 300mm x 300mm and is kept at a constant surface temperature of 200°C. When the press is retracted, т RT air flows over the plate at 1.5. Determine the heat power required to keep the copper plate at a constant temperature.
