- Q3) A compressor, requiring 90 kW is to run at about 250 r.p.m. The drive is by V-belts from an electric motor running at 750 r.p.m. The diameter of the pulley on the compressor shaft must not be greater than 1 meter while the centre distance between the pulleys is limited to 1.75 meter. The belt speed should not exceed 1600 m/mi. Determine the number of V-belts required to transmit the power if each belt has a cross-sectional area of 375 mm² density 1000 kg/m and an allowable tensile stress of 2,5 MPa. The groove angle of the pulley is 35°. The coefficient of friction between the belt and the pulley is 0.25.1- A steam stripper is used to help removing wallpapers. It comprises of a tank of waterwith an electrical heating element. To generate steam, from which a long rubber tubeconveys the steam to the head which contact with the wallpaper to be removed.(i) The power rating of the electrical heating element is 2 KW, and the tank holds about3 liters of water. Estimate the time it would take from switching the power on tosteam to be generated. (ii) Once steam has started to be produced, estimate how long you could workcontinuously before having to refill the tank. Assume that all water initially in thetank can be evaporated into steam. Also, neglect any heat loss from the tank.Data :Room Temperature 20 oCHeat capacity of water, Cp 4.19 KJ kg-1 K-1Latent heat of vaporization of water at 100 oC, hfg 2257 KJ kg-1(iii) Stream is to be condensed in the condenser of a steam power plant at atemperature of 50 oC with cooling water from a nearby lake which enters the tubesof the condenser at 18 oC at…3. Please calculate the annual electricity production of a wind farm with 20 turbines. The annual mean wind speed is 7 m/s and diameter of the blades is 20 m. If we assume power consumption of a person is 3,000 kWh, about how many people will this energy support? Annual electricity production (KWh) = K Vm³ At T Where: - - - K = 3.2 (factor based on turbine performance) Vm= annual mean wind speed (m/s) At = swept area of turbine (m2) T = number of turbines Suitable for medium- to large-scale wind turbines (> 200 m2 swept area)
