To determine permeability number of green sand, core sand and raw sand
During a permeability test, the pressure reading on the manometer is lower than expected. What does this indicate? (LO1)
How does increasing sand grain fineness (higher GFN) affect permeability? (LO4)
Why is proper ramming of sand important in permeability testing? (LO2)
Which factor can negatively impact the permeability of moulding sand? (LO1)
What is a likely consequence of using sand with extremely high permeability? (LO1)
