answer the following question correctly
Saturated steam coming off the turbine of a steam power plant at 30°C condenses on the outside of a 3-cmouter-diameter, 35-m-long tube at a rate of 45 kg/h. Determine the rate of heat transfer from the steam to the cooling water flowing through the pipe.
The evaporation rate from the surface of a 3650-acre lake is 100 acre-ft/day. Estimate the depth change in the lake in feet during a 1-year period if the net inflow to the lake is 25 cfs. Is the depth increasing or decreasing? What is the change in c..
