Consider a flat plate subject to parallel flow (top and bottom) characterized by u 5 m/s, t 20 c. (a) determine the average convection heat transfer coefficient, convective heat transfer rate, and drag force associated with an l 2-m-long, w 2-mwide flat plate for airflow and surface temperatures of ts 50 c and 80 c. (b) determine the average convection heat transfer coefficient, convective heat transfer rate, and drag force associated with an l 0.1-m-long, w 0.1-m-wide flat plate for water flow and surface temperatures of ts 50 c and 80 c

An ideal rankine cycle with reheat uses water as the working fluid. the conditions at the inlet to the high pressure turbine are 10mpa, 650°c and the steam is reheated at a constant pressure of 1.4mpa before entering the low pressure turbine. for a condenser pressure of 10kpa, plot the cycle thermal efficiency and quality of steam at the low pressure turbine exit versus reheat temperatures (the temp of steam entering the low pressure turbine) of 400, 500, and 600°c. draw the t-s diagram and show all your work for a reheat temperature of 400°c .note, there will be two plots. one with thermal efficiency on in the ordinate versus reheat temperate and the other will have quality on the ordinate versus reheat temperature. be sure to label all axes with variables and units and include title. the plots must be done on computer.
