    The Reynolds number for ethyl alcohol is 91,510

    Explanation:

    Reynolds number (Re) = density*velocity*diameter/viscosity

    density of ethyl alcohol = 789kg/m^3, velocity = 5m/s, diameter = 1 in = 0.0254m, viscosity of ethyl alcohol = 0.001095Pa. s

    Re = 789*5*0.0254/0.001095 = 91,510
