As shown in the diagram, a pump draws a liquid from a storage tank to (point 1 ) and discharges to an overhead tank (point 2). The liquid velocity through the suction pipe is 2m/s and through the discharge pipe is 4m/s. The end of discharge pipe is at 20m above the level of liquid in thi storage tank. The losses due to friction in thi entire system is 30J/kg. If the efficiency of thi pump is 65%, a) What is the power of thi pump? Assumptions: 1) take point 1 at the surface of the liquid in the tank and point 2 at the discharge end, 2) take the datum plane for elevations through point 1,3 ) Kinetic energy correction factor can be taken as 1 . This is a subjective question, hence you have to write your answer in the Text-Field given below. One wall consists of three layers, 1) outer brickwork 15cm thick, 2) intermediate insulating layer of 7cm thick and 3) inner wooden layer 1.2cm thick. Inside temperature of the wall is 21C and outside temperature of the composite wall is 15C. The intermediate insulating layer offers double thermal resistance of the outer brick layer. a) Calculate the rate of heat loss through the wall per unit area. b) Calculate the thermal conductivity of the insulating layer. Given: thermal conductivity of brick is 0.70W/mC, wood is 0.18W/mC For water flowing over a flat plate at 15C and 1.2m/s. a) Calculate Reynolds number at a distahte of 5cm from the leading edge of the plate. b) Identify the type of flow. c) Calculate Prandtl number. d) compare thermal boundary later and momentum boundary layer. Given: Water density is 1000kg/m3, water viscosity is 1.13103kg/m.s, specific heat of water is 4200J/KgK, thermal conductivity of water is 0.6W/mK This is a subjective question, hence you have to write your answer in the Text-Field given below. 10 marks a) A black body has a maximum wavelength of 600nm at 3000K.
