Hot forging is used to reduce a metallic cylindrical workpiece with a diameter of 12 cm and height of 24 cm to a height of 15 cm. The coefficient of friction of the open die plate with the workpiece is 0.18 and the process takes 4 seconds to complete and at a constant speed. The strength coefficient of the workpiece C= 180 MPa and strain rate sensitivity exponent m = 0.25. calculate the following:

The forging shape factor at the end of the process.
The maximum flow stress (MPa).
The maximum forging force (N).
The power (W) required to complete the process.
