A Pump Is Transferring Water From A Large Lake To The Top Of An Empty Tank That Is Open To The Atmosphere Via An Exten 1 (41.78 KiB) Viewed 48 times

A pump is transferring water from a large lake to the top of an empty tank (that is open to the atmosphere) via an extensive pipeline network. The pipe network consists of 1000ft of straight pipe, 890∘ elbows, 3 gate valves that are 100% open and 1 flow meter for monitoring the flow rate. The pipe is made from commercial steel and the diameter is 4 inches. The water temperature is 70∘F and the water flow rate is 500 gallons per minute. For this process you may assume elevational differences are negligible and the pipe length for the pump suction is also negligible. Vendor data for the flow meter estimated the pressure drop through this device is approximately 10lbf/in2. The viscosity of water is 2.05×10−5lbfsec/ft2 and the density of water is 62.4lbm/ft3. Calculate the Reynolds number (10 points) Calculate the relative roughness (10 points) Calculate the friction factor (10 points) Calculate the discharge pressure of the pump (10 points) Calculate the horsepower requirements for the pump. (make sure the final units are in horsepower (hp) )(10 points)
