Question
An engineering research company is evaluating using a sophisticated $80,000 laser system between two large water storage tanks. You suggest that the job can be done with a $200 manometer arrangement. Oil less dense than water can be used to give a significant amplification of meniscus movement; a small difference in level between the tanks will cause a much larger deflection in the oil levels in the manometer. If you set up a rig using Meriam red oil is the manometer fluid, determine the amplification factor that will be seen in the rig.Explanation / Answer
densitity of meriam red oil is 0.827 let increase in water level in water tank at left be h hence by that let the increase in level of oil in in left arm by t hence by balancing pressure at phase change boundary ?1*g(h+t) =?2 *2*t*g hence h/t +1 =2*?2/?1 ?1 =1 , ?2=0.827 hence h/t+1 = 1.654 hence h/t =0.654 hence amplification =t/h =1/0.654 =1.53
