1. The problem statement, all variables and given/known data Two cylindrical pipes both carry an ideal fluid (zero viscosity) in laminar flow. Pipe A has radius Ra = 2 and flow velocity Va = 8cm/s. Pipe B has radius Rb = 4cm and flow velocity Vb = 4cm/s. A) Calculate the cross section of pipe A and pipe B. B) Calculate the rate of flow in liters/second (1l = 1000cm cubic) 2. Relevant equations maybe v1a1 = v2a2 ? 3. The attempt at a solution v1a1 = v2a2 = (8cm/s)(2cm) = (4cm/s)(4cm) = 1 ? It`s wrong.
