A concentric cylinder viscometer is driven by a falling mass M connected by a cord and pulley to the inner cylinder, as shown. The liquid to be tested fills the annular gap of width a and height H. After a brief starting transient, the mass falls at constant speed Vm. Develop an algebraic expression for the viscosity of the liquid in the device in terms of M, g, Vm, r, R, a, and H. Evaluate the viscosity of the liquid using: M = 0.10 kg r = 25 mm R = 50 mm a = 0.20 mm H = 80 mm Vm = 30 mm/s
A rocket nozzle has a chamber pressure of 20 Bar (2 MPa) and a chamber temperature of 2750 K. The rocket is designed to operate isentropically at 12,500 m altitude. Note that the pressure at 12,500 m can be estimated using this equation P/P0 = exp [-..
