Apitot-static probe is mounted in a 2.1-cm-inner diameter pipe at a location where the local velocity is approximately equal to the average velocity. the oil in the pipe has density ρ = 860 kg/m3 and viscosity μ = 0.0103 kg/m⋅s. the pressure difference is measured to be 95.8 pa. calculate the reynolds number of the flow. is it laminar or turbulent?
