A centrifugal pump is running at 1000 rpm delivers water against a net head of 7 m. The blade angle at outlet is 28° with the direction of peripheral velocity. The diameter and width at the outlet of impeller are 0.25 m and 50 mm respectively. Calculate (a) discharge, and (b) power required for running the pump. Assume manometric and overall efficiency as 90% and […]
1.Why are many consumers apt to be rationally ignorant about their options? 2.Why would insurance coverage tend to increase rational ignorance? 3.A proposal has been advanced to limit advertising of pharmaceutical prices to prevent unfair pricing by national chains. You estimate that limits on price advertising will change the price elasticity of demand from _5.63 to _4.43. The marginal cost of a typical prescription is […]

A centrifugal pump is working against a head of 51 m while running at 1000 rpm. The vanes on the impeller are bent backwards with an exit angle of 30° and the velocity of flow across the impeller is constant at 2.4 m/s. The diameter and width of the impeller at outlet are 0.48 m and 60 mm respectively. The external diameter of the impeller […]
1.Hospital privileges usually restrict what physicians can do. Medical licenses do not. What drives this difference? 2.Consumers Union, the Leapfrog Group, and the Department of Health and Human Services have websites that provide consumer information about hospitals. Why are there multiple sources of information? Which of these sources did you find the most interesting?
An ice-making plant is working on a reversed Carnot cycle heat pump. It produces 15 tonnes of ice in 24 hours. The ice formation is from water at 0 _C and maintained at the same temperature. The heat rejection is at 27 _C to the atmosphere. The heat pump runs the ice plant coupled to a Carnot engine which absorbs heat from a source which […]
