The tools to be used are the basic applications for mass, energy and momentum balance. I MUST present the calculation algorithm and its numerical results. No just results.

A pressure drop of 700 kPa is measured along a horizontal iron pipe.forged 10 cm diameter 300 meters in length that transports an oil (SG = 0.9 and 10-5 m2/s). It is requested to calculate the flow (m3/s) that circulates through the duct.
