Problem 3: Momentum Balance For the dental device shown in Problem 1 the inlet pressure is 48 psig. The velocity ana dimensions are the same as in Problem 1. 2.0 1.6 NH,HCO3 NaHCO, 1.2 0.8 0.4 0.0 0.0 0.5 1.0 1.5 2.0 2.5 Concentration, moll 1 Stoke (St) = 1 Poise (P) divided by density of the fluid in g/cm³ A. What is the force require to hold the dental device, such that it does not move (steady)? Provide in boxes the force with direction first, then magnitude. B. How does this force needed to hold the dental device steady compare to the strength of the average human hand? 4 Viscosity, cSt

One can has your teeth cleaned professionally using Problem 1: Reynold's number a rotating brush or with a jet stream oi a baking soda slurry. For baking soda slurries, the dentist uses a device similar to the device shown in HD Figure 8.24 to remove plaque. The fluid used in the device is a baking soda slurry. Baking soda slurry is 3.0% baking soda (sodium bicarbonate) in water, where 0.90% is the saturation limited of baking soda in water. If the inlet velocity is 0.24 m/s with inlet diameter of 5.4 mm at 23°C. The nozzle tip has a diameter of 0.51 mm. Assume no frictional effects. See page 4 for sodium bicarbonate-viscosity graph. State any other assumption needed. FIGURE 8.24 Inlet Flow Outlet Q Flow
