I need a clear answer by hand, not by keyboard | dybala

4.2. A 16 ft wide sand bed stream (Sf = 0.002, n'= 0.015, with smooth channel banks) has
the following particle size distribution for its bed sediment:
Accumulated Finer, % 0.07 0.33 2.0 7.2 21 36 55.5 75.4 88.4 99.3
Sieve Opening, mm 0.05 0.13 0.27 0.32 052 0.71 0.89 1.3 1.95 3.50
Build your calculations for water depth of 0.35 ft with corresponding unit discharge of 0.65
ft/sec. Use Ss=2.65, p=1.934 #s/ft' and v=0.989 x 10 ft/s for water. Find the
following by choosing the correct answer:
2- The d65 from particle size
distribution curve is equal to:
1.25 mm
