fluid has a mass of 1500 kg and a volume of 1.85 cubic meter. a.) What is the specific gravity of the fluid ? b.) What is the unit weight of the fluid?

Question 3 Calculate the dry rodded unit weight (density), apparent specific gravity, bulk specific gravity oven dry, and bulk specific gravity at SSD for the following two aggregate samples. a) An aggregate sample from a stockpile A has a mass of 35.09 lb. When oven-dried, it has a mass of 33.14 Ib. When brought to a saturated surface dry state it has a mass of 35.18 Ib. When weighed in water, it has a mass of 20.23 lb. A 0.35 ft.³ bucket filled with an oven-dry sample of the aggregate weighs 33.14 lb. b) An aggregate sample from a stockpile A has a mass of 8.93 kg. When oven-dried, it has a mass of 7.4 kg. When brought to a saturated surface dry state it has a mass of 7.87 kg. When weighed in water, it has a mass of 4.35 kg. A 0.009 m.3 bucket filled with an oven- dry sample of the aggregate weighs 13.9 kg.

What is the Mach number of a plane traveling at a) 1020 m/s b) 170 m/s and c) 1836 km/h of thefollowing speeds at sea level in air with a temperature of 12 degrees celsius?

A pipe has a cross-sectional area of 16.5cm2 at point A, where the speed of the fluid (water) is 1.2 m/s and the pressure is 2.00 atm. The pipe ascends 3.00 m and narrows to 8.20 cm2 at point C. a) what's the speed of the fluid at point C. b) what's the absolute pressure at point C.
