5. In Fig. P4.5 the flowing fluid is CO2 at 20°C. Neglect losses. IfPi = 170 kPa and the manometer fluid is Meriam red oil (SG 0.827), estimate (a) P and (b) the gas flow rate in m/h Air: p 20 lbf/in2 abs Po = 14.7 blin2 abs P(4.5) 3. The power input P to a centrifugal pump is assumed to be a function of the volume flow Q, impeller diameter D, rotational rate Ω, the density p, and viscosity...

a) Describe the following types of flow and give one example: i) Steady uniform flow (2 marks) i) Unsteady uniform flow (2 marks) i) Unsteady non-uniform flow (2 marks) b) The power input P to a centrifugal pump is assumed to be a function of the volume flow Q, impeller diameter D, rotational rate 0, and the density p and viscosity u of the fluid. By using 0, p and D as repeating variables, develop this as a dimensionless relationship....

Density p [kg/m2], viscosity - u [kg/ms], surface tension - o (N/m=kg/s2] compressibility K [Pa-kg/ms2] 1. For particles settling in a stationary fluid it is thought that the drag force FD of a small sphere is a function of the settling velocity of the sphere - V, the diameter of the sphere - d, and the density p, and viscosity of the fluid - . Determine the dimensionless relationship(s) between these variables (FD/HVd, pdV/H) 2. (a) The efficiency of a...

The pump process can be described by three r terms as ΔΙ1D where P = power (FLT-1), ρ = density of the fluid (FL-4T2), N-angular speed of the rotor (T-1), D = diameter of the rotor (L), Δ11D = Head (L), Q = volume flow rate (L3T", The relationship in dimensional form would be expressed as P = φ(p, D, N, ΔΙΌ.Q) Using the Buckingham π-theorem, obtain the first and the third π-terms of the non-dimensional relationship. Use ρ, D,...
