water at 20degC is flowing in a horizontal pipe that is 20m long. the flow is laminar and the water completely fills the pipe.A pump maintains a gause pressure of 1400pa,at a large tank at one end of the pipe.The other end of the pipe is open to the air,The viscosity of water at 20degC is 1.005poise. (a)If the pipe has diameter 8cm ,what is the volume flow rate? (b)What gauge pressure must the pump provide to achive the same volume flow rate for a pipe with a diameter of 4cm? (c)For a pipe in part (a) and the same gauge pressure maintened by a pump,what does the volume flow rate become if the water is at a temperature of 60degC (the viscosity of water at 60degC is 0.469poise) ans-(a)7*10^-4m^3/s (b)2.24*10^4Pa (c)0.5*10^-3 m^3/s how???????????
