 gc 2 gc 2Establish SP1 on the upstream surface of the water and SP2 on the downstream surface. There isno heat added between the SPs, therefore Q 12  0 . The temperature of the water does notchange appreciably, so the internal energy (u) does not change, nor does the specific volume ofthe water (v). The pressure on both free surfaces is atmospheric pressure. Therefore the changein u (u) and flow work (pv) each cancel. Establish the reference elevation at the downstreamsurface (SP2). Therefore z2 = 0. There is a downstream velocity. Convert the 10 mph to 14.67ft/sec. Eliminating terms that either cancel or are negligible results in the following:  gz   V2 2
