A straight horizontal pipe with a diameter of 1.0 cm and a length of 47 m carries oil with a coefficient of viscosity of 0.13 N · s/m2. At the output of the pipe, the flow rate is 8.3 10-5 m3/s and the pressure is 1.0 atmosphere. Find the gauge pressure at the pipe input. atm A thin 1.8-mm coating of glycerine has been placed between two microscope slides of width 1.0 cm and length 4.0 cm. Find the force required to pull one of the microscope slides at a constant speed of 0.29 m/s relative to the other slide. A pipe carrying 20°C water has a diameter of 3.7 cm. Estimate the maximum flow speed if the flow must be streamline.
