fluid and heat transfer

1- Water at 15 degrees C(=1000kg/m3,=1.3103kg/ms) is flowing steadily in a 30m long, 4-cm-diameter horizontal pipe. The pipe is made of stainless steel with a roughness [=0.002mm. The flow rate is 0.008m3/s. Find the pressure drop. 1- Water at 15 degrees C(=1000kg/m3,=1.3103kg/ms) is flowing steadily in a 30m long, 4-cm-diameter horizontal pipe.
