Problem 7 Consider a fluid flows at standard atmospheric pressure in a one-inch diameter pipe. a) What would be the fluid velocity if the flow is to be laminar. Fluid maybe water, air, or oil b) Is it practically realistic that flow will be laminar in case of water, air or oil? c) Approximately how long is the entrance length in this pipe? Find for water, oil and air.
