H4-2: As shown below, water (which has a density of 998 kg/m2) flows steadily through a box, entering section 1 at 2 m/s. The inlet and exit are both open to atmosphere. Neglect body forces. Calculate the (a) horizontal; and (b) vertical forces required to hold the box stationary D1=5cm 65° D2=3cm hswers: (a
Water (density 998 kg/m', absolute viscosity 1.12x10 Ns/m2) is pumped from a lake into a reservoir at a rate of 0.7 m/s. The water flows through a re-entrant opening, a valve, and a sharp-edge...
Water (density 998 kg/m', absolute viscosity 1.12x10 Ns/m2) is pumped from a lake into a reservoir at a rate of 0.7 m/s. The water flows through a re-entrant opening, a valve, and a sharp-edged exit, which have loss coefficients of 0.8, 10, and 1, respectively. The pipe has an absolute roughness of 1x104m and di of 0.30 m. The pump efficiency is 65%. A) Is the flow in the pipe laminar or turbulent? (2 points) B) What is the power...

Water (density 998 kg/mº, dynamic viscosity 0.001 Pa s) is pumped between two reservoirs at a volumetric flow rate of 0.006 m/s through a 120-m long pipe of 5 cm diameter. The roughness ratio of the pipe is a/d = 0.001. There are some fittings and valves in the pipe system, as shown in Figure Q1. The loss coefficients of the valves and fittings can be found in Table Q1. The Darcy friction factor can be found in the Moody...

"Oceanographers are not so much interested in the absolute density of the water but in density changes in space and time. Such changes are quite small. Oceanographers therefore use the quantity_0 = p - 1000 (pronounced sigma-tee = density minus 1000), which gives the density excess or deficit against a reference density of 1000 kg m3. In principle, Ot should have the same unit as p (kg m-3); but oceanographers never give units with ot. Thus, freshwater has a Ot...
