200 kg/min of steam enters a turbine at 40 bar with 100 degrees of superheat through a 7.5 cm diameter pipe and exits as saturated water at 5 bar through a pipe of the same diameter after expanding adiabatically. the inlet and outlet pipes are at the same vertical height. how much work (in kw) is produced by the turbine? hint: do not neglect the change in kinetic energy between the inlet and outlet.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
