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

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
