Question
A constant-head permeability test was conducted on a clean sand sample. 
The diameter and length of the test specimen were 150 and 180 mm, respectively. 
The head difference between manometer levels was 62 mm during the test, and the water temperature was 24°C.
 If it took 5min for 1000 mL of water to discharge and the void ratio of the sand was 0.75 
1)     The coefficient of permeability of the sample at 24°C in cm/s         
2)     The coefficient of permeability of the sample (at 20°C) in cm/s               
3)     The velocity of water moving through the soil in cm/s                                
4)     The actual velocity of water moving through the soil in cm/s
