A) Compute the runoff for a 7-in rainfall on a 1500-acre watershed that has hydrologic soil groups that are 40% group A, 40% group B, and 20% group C interspersed throughout the watershed. The land use is 90% residential area that is 30% impervious, and 10% paved roads with curbs. Assume AMC II conditions. B) What was the runoff for the same watershed and same rainfall before development occurred? The land use prior to development was pasture and range land in poor condition

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
