A group is considering installing a solar power station and has asked you for your recommendation if it should be a photovoltaic system or a solar thermal system. At this stage you are asked not to include cost factors. The single point design condition they have given you is for an incident solar radiation on the collector of 550 W/m2, a surrounding temperature of 18 C. The dead state for this problem should be taken as To = 291 K, Po = 1 bar. You can perform your analysis at steady state conditions. In addition to determining the power output and first law efficiency of the options, you have been requested to determine the exergy destroyed for each of them. The photovoltaic system has an efficiency of 0.15 defined as the power output/incident solar radiation. The basic photovoltaic collector is 1.1 m2 and losses heat from both the front and back surface. The edge area can be neglected. The convective heat transfer coefficient is 10 W/m2 K. The inverter and signal…
Q5 A) A power transistor has a temperature on its face exposed to environment of 80 °C, its thickness is 10 mm. Its radius is 2 cm. The convection heat transfer coefficient is 200 W/m2.K, its thermal conductivity is 200 W/m K. How much heat could be dissipated by the power transistor assume the environmental temperature is 20 °C. Q5 B) An instantaneous laser pulse of 7.5 MJ/m2 is imposed on a slab of Aluminum initially at uniform temperature of 40 °C. Calculate the temperature at the surface after 2s.
A block of 3 kg, initially at rest, is pushed uphill on an incline of 30 degrees over a distance d,. The pushing force is directed horizontally and has a constant magnitude of 35 N. The surface of the incline offers a constant kinetic friction (µk = 0.3). a) Make a FBD for the block and use Newton's 2nd law to find the normal force and the friction. b) Use work-energy approach to calculate how much farther the block moves uphill after we stop pushing (this distance (d,) should be expressed as a proper or improper fraction of the "pushing distance"(d,) – I am not asking for a number!!). Take as your SYSTEM: BALL+INCLINE+EARTH. Make sure to make lists of all the forces that are relevant and to calculate the work done by each of them, as seen in the lectures.
