Water at atmospheric pressure and temperature (rho = 998.2 kg/m3, and mu =1.003

Question

Water at atmospheric pressure and temperature (rho = 998.2 kg/m3, and mu =1.003 times 10 -3kg/m middot s) at free stream velocity V = 0.100481 m/s flows over a two-dimensional circular cylinder of diameter d = 1.00 m. Approximate the flow as potential flow. (a) Calculate the Reynolds number, based on cylinder diameter. Is Re large enough that potential flow should be a reasonable approximation? (b) Estimate the minimum and maximum speeds |V|min and |V|max (speed is the magnitude of velocity) and the maximum and minimum pressure difference P - P infinity in the flow, along with their respective locations.

Explanation / Answer

Re= 9.98E^5 which is bigger than 1e^5 so yes reasonable assumption b) -15.21 I will get you the explination and a step-by step solution
