Question

Consider the table where the primary dimensions of several variables are listed in the mass– length–time system. Some engineers prefer the force–length– time system (force replaces mass as one of the primary dimensions). Write the primary dimensions of three of these (density, surface tension, and viscosity) in the force– length–time system

Every few years, winds in Boulder, Colorado, attain sustained speeds of 43.0 m/s (about 100 mph) when jet steam descends during early spring. Approximately what is the force due to the Bernoulli equation on a roof having an area of 220m2? Typical air density in Boulder is 1.14kg/m3, and be corresponding atmospheric pressure is 8.89104 N/m2. (Bernoulli’s principal as stated in the text assumes laminar flow. Using the principle here produces only an approximate result, because there is significant turbulence.)
In an immersion measurement of a woman's density, she is found to have a mass of 62.0 kg in air an apparent mass of 0.0850 kg completely submerged with lungs empty.

(b) What percent of her volume is above surface when she floats in seawater?
What is the pressure drop due to the Bernoulli Effect as water goes into a 3.00-cm-diameter nozzle from a 9.00-cm-diameter fire hose while carrying a flow of 40.0 L/s? (b) To what maximum above be nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.)

(a) What minimum diameter must be pipe have if the Reynolds number is to be less 2000? (b) What pressure difference must be along each kilometer of be pipe to maintain flow rate?
