In a lab experiment, pure methane at a pressure of 3 atm and room temperature is pumped through the circular end of a small cylindrical core plug with cross-sectional area 1 cm^(2), length 1 cm, and permeability 100 mD. The pressure at the output is 1 atm. What is the volumetric flow rate at the output? Use Darcy's Law

An electric motor is used to drive a power press which makes steel turning moment diagrams 323 pressings from a metal sheet. the motor runs at a mean speed of 50 rev/s. the torque required is 10.0nm for 0.2s, followed by 1.0nm for0.3 s with this sequence then being repeated. what is the minimum power required of the motor and the moment of incrtia required for the t1ywhcel if the speed fluctuations are to be restricted to 1.5%?
