Infiltration fields test using the double ring infiltrometer and under continuous ponding of the ground surface, were conducted at a number of \( \mathrm{pf} \) locations in Florida City, Florida. The engineer in charge analyzed the test results concluding that the Horton's equation fitted the results well and providing the following parameter for one of the locations - Soil type at location No.2345: Donan Loany Sand - \( \mathrm{F} 0=6.0 \mathrm{in} / \mathrm{hr} \) \( -\mathrm{Fc}=1.8 \mathrm{in} / \mathrm{hr} \) \( -\mathrm{K}=6.50 \mathrm{~h}-1 \) 12. Calculate the potential infiltration rate in in/hr \( 340 \mathrm{~min} \) after the start is about a) none b) \( 6.0 \mathrm{in} / \mathrm{hr} \) c) \( 1.8 \mathrm{in} / \mathrm{hr} \) d) \( 0.2 \mathrm{ft} / \mathrm{hr} \) e) \( 0.9 \mathrm{in} / \mathrm{hr} \) 13. Calculate the cumulative infiltration in inches, \( 340 \mathrm{~min} \) after the starts is about f) a) none g) b) \( 5.4 \) in h) c) \( 15.3 \) in i) d) \( 10.9 \) in j) e) \( 2.4 \) in
