Question
1. (5 pts) A 1m diameter vat of liquid is 2m deep. The pressure at the bottom of the vat is 1.3atm. What is the mass of the liquid in the vat? (figure below) 2. (10 pts) Water flows at 5L/s through a horizontal pipe that narrows smoothly from 10cm diameter to 5cm diameter. A pressure gauge in the narrow sections reads 50 kpa. What is the reading of the pressure gauge in the wide section? (figure below) 3. (5 pts) A 6cm diameter sphere with a mass of 89.3 g is neutrally buoyant in a liquid. Identify the liquid. (Hint, Use table 13.1) 4. (5 pts) A standard gold bar stored at fort Knox, KY is 7inches long and 3.63 inches wide and 1.75 inches tall; Gold has a density of 19300 kg/m^3. What is the mass of such a gold bar?Explanation / Answer
4)
Density = Mass/Volume
hence Mass = Density x Volume
Density = 19300 Kg/m
on inch = 0.0254 m
and Volume = l x b x h = 7 x 3.63 x 1.75 x (0.0254)3
= 72.87x10-5
hence Mass = 14.064 Kg
