Determine the flow rate of air through an axial bush seal. The outer diameter of the inner cylinder is 250 mm and the radial clearance is 0.2 mm. The length of the seal is 100 mm. The pressures upstream and downstream of the seal are 1.5 and 1.01 bar, respectively. The viscosity of air can be taken as 1.85 x 10 SPas. m/s

Expert Solution
Step 1

Given data:-

The outer diameter of inner cylinder, D=250 mm1 m1000 mm=0.25 m

Radial clearance, c=0.2 mm1 m1000 mm=0.0002 m

Length of seal, L=100 mm1 m1000 mm=0.1 m

The pressure upstream of the seal, Po=1.5 bar105 Pa1 bar=1.5×105 Pa

The pressure downstream of the seal, Pa=1.01 bar105 Pa1 bar=1.01×105 Pa

The viscosity of air, μ=1.85×10-5 Pa-sec
