Water at 15°C is flowing in a 30-m-long horizontal pipe made of stainless steel. If it flows at a rate of 9 litre/s, what is an effect of the pipe diameter on the pressure drop? To assess your answer in WS04: [Part B] Question 02, plot a graph of AP(kPa) vs diameter (m) Functions to calculate Re and fanning friction factors are provided here. In order to implement them, please follow the specific orders. Re=ReynoldsNumber(V,D,rho,mu) f_F=fanningFrictionFactor(Re, epsilon,D) To store numerical values, please name Temp_'. For example, velocity will change with a different diameter. To store velocities, name it Temp_V. In the same manner, you can name Temp_Re to store Re values.For pressure drops, name it del_P.
