An аnnulus оf nаrrоw cleаrance causes a large pressure drоp and can be used to measure fluid viscosity accurately. A smooth annulus has: L=1.0 m,a=50 mm,b=49 mmL = 1.0 text{m}, qquad a = 50 text{mm}, qquad b = 49 text{mm}Oil flows through the annulus at Q=2.60×10−3 m3/s Q = 1.400times10^{-3} text{m}^3/text{s} If the measured pressure drop is Δp=250 kPaDelta p = 250 text{kPa} What is the oil viscosity μmu in kg/m.s?
