[5 points] The rapid sand filter being designed for Sandusky has the characteristics and sieve analysis shown below.

Depth = 0.85 m

Filtration rate = 230 m3/d-m2

Sand specific gravity = 2.5

Shape factor (Sphericity) = 0.8

Stratified bed porosity = 0.6

Water temperature = 19°C

Acceleration due to gravity = 9.81 m/s2

If the summation of is equal to 48,000, what is the clean bed headloss? Use the Rose equation.
