4. 5.10 from textbook the dynamic behavior of the liquid level in a leg of a manometer tube, responding to a change in pressure, is given by where h′(t) is the level of fluid measured with respect to the initial steady-state value, p′(t) is the pressure change, and r, l, g, rho, and μ are constants. (a) rearrange this equation into standard gain-time constant form and find expressions for k, τ, ζ in terms of the physical constants. (b) for what values of the physical constants does the manometer response oscillate? (c) would changing the manometer fluid so that rho (density) is larger make its response more oscillatory, or less? repeat the analysis for an increase in μ (viscosity).
