What height in meters of a column of a special gage liquid having a specific gravity of 2.90 would exert the same pressure as a column of oil 6 m high having a sp.gr. Of 0.80. a. 2.48 m b. 1.24 m c. 1.86 m d. 1.66 m

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.

Rover weight capacity 35 kilo grams (payload)Rover measurements:Wheel distance - 14.5 inches and 8.5 inchesRover platform size (width & length) 14.4 inches x 10.4 inchesHeight- 15.8 inches   Water tank selectionMore or less 25 liters*For tank selection we need to justify the size with the center of gravity, proving that is themaximum dimension or liters of the tank because the center of gravity will be higher makingthe rover prone to topplingPump selection*Our sprayer design has two nozzles which splits using a tee splitter, we need to find thesize of the pump to obtain the same discharge rate of a normal sprayer. A normal sprayerhas a 12V pump and a pressure from 0.2 to 0.45 mpa (30-65 psi)The application rate of the main pesticide is 9.6 - 19.2 fl oz/A (Brigade Insecticide for sweetpotato)Thai was the initial deign where the water tank is above the battery and pump, but wechanged our mind, now it is the battery and pump above the waterBattery selection* once the size of the pump…
