Parallel flow of air over a flat plate of length 3m is disrupted by an array of stationary rods placed in the flow path over the plate. an empirical correlation for the local heat transfer coefficient is obtained for a velocity, v and ts> [infinity]t: hx=0.7+13.6x-3.4x2, where hx has units of w/(m2*k) and x is in meters. evaluate the average heat transfer coefficient for the entire plate and the ratio llh/h at the trailing edge. also plot the heat transfer coefficient as a function of x (from x=0 to x=3m). how does this plot compare to flow over a flat plate without any stationary rods?

Ahouse has the following electrical appliance usage (1) single 40w lamp used for 4 hours per day (2) single 60w fan used for 12 hours per day (3) single 200w refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours find the solar power inverter size in watt with correction factor of 1.25.

Agas mixture consists of 8 kmol of h2 and 2 kmol of n2. determine the mass of each gas and the apparent gas constant of the mixture.

Steam at a pressure of 100 kpa and a quality of 50% initially fills a rigid vessel having a volume of 0.5 m^3. the steam is then heated, causing the pressure in the vessel to rise to 150 kpa. determine: i. the mass of the steam in the vessel. ii. the temperature and quality of the steam after the heating process. ii the mass of the vapour, mg and liquid, m in the vessel after the heating process. if the steam in the vessel is now further heated, what would the pressure and temperature in the vessel be when all steam has turned into saturated vapour? b. sketch the processes in part (a) and part (b) on p-v and t-v diagrams, indicating clearly the temperatures, pressures and the paths. c.
