During a given year, a 60 mi2watershed received 35 inches of rain. In that same time period 22,400 ac feet of surface water runoff was measured by integrating the runoff hydrograph from a USGS gaging station. What is the mean annual flow at the gage in cfs?

What percentage of the rainfall resulted in direct surface water runoff?

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
