Head Loss Calculation What is the head loss along a 1000 m straight pipe (inside diameter: 0.2 m) that delivers water (kinematic viscosity: 1 x 10° m²/s) at 0.032 m³/s? Absolute roughness of pipe = 0.1 mm.

Water at 60 degrees Fahrenheit have a density of 62.36 Ib/ft.^3 and dynamic viscosity of 7.536 x 10^-4 Ib/ft-s) is flowing steadily in a 2-inch diameter horizontal pipe made of stainless steel at a rate of 0.2 ft^3/s. Use f = 0.0200. Determine %3D the head loss in terms of inches over a 200-feet long section of the pipe. A) 327.60 В 27.30 C 376.05 D None of the above

please solve the problem in the picture

Oil flows through a circular pipe at a rate of 0.4m^3/s.  Density p= 960kg/m3  Length of Pipe = 120m Head loss along the length = 7m Roughness of the pipe, ks = 0.07mm Kinematic viscosity v= 2 x 10^(-5)  m2/s Find the diameter of the pipe to 3dp. (The final solution should be 0.34m, but i am confused with the method so if you could put a few notes next to calculations that would be very helpful). Ive attached a copy of the moody diagram aswell as it is relevant.
