Given an initial infiltration capacity f0 of 3.0 in/hr and a time constant k of 0.29 hr-1. drive an infiltration capacityversus time curve if the ultimate infiltration capacity is 0.55 in./hr. for the first 10 hours.
a). estimate the total depth of water infiltrated in inches over the watershed assuming that the rainfall intensity, i(t)=3.2 in/hr for a one hour duration storm
b). estimate the total depth of water infiltrated if i(t)=0.75 in/hr for a ten hour storm.
c). estimate the total depth of water infiltrated over the watershed if a two hour storm was 0.5 in/hr from 1: 00-2: 00, 1 in/hr for 2: 00-3: 00, 5 in/hr for 3: 00 to 3: 30.
d). calculate the phi index for the storms in a-c, if the watershed is 2000 ac.

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
