Air at 200 kpa enters a 2-m-long, thin-walled tube of 25-mm diameter at 150°c and 8 m/s. steam at 20 bars condenses on the outer surface. determine the outlet temperature and pressure drop of the air, as well as the rate of heat transfer to the air. evaluate the properties of air at tm=450 k

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
