Water flows into a tank and out through another pipe, as shown in the figure below. The water in the tank has a surface area, Asurf = 4.6 m². At the bottom of the tank there is a door inclined at an angle = 30 degrees with respect to the horizontal. The door has a length L=0.8 m and a width w=1 m (out of the page). The flowrate into the tank is Qi (t) = 0.16999999999999998 m³/s and the flowrate out is Qo(t) = 0.05 m³/s At time t - 0, the water has a depth ho = 2.1 m. The density of water is p = 1000 kg/m³.

8) A) A rectangular plate with dimensions 3m x 5m is submerged horizontally in a pool of water. Find the fluid Force on one side of the plate if it is 2m below the water's surface. Ans: 147000 J b) Find the Force on one side of the plate if it is submerged vertically and the edge of the plate is 2m below the surface. Ans: 661500J 9) Find the COM of the region under f(x)= 6-2x, [0, 3] Ans: (1, 2)

An aircraft flying at a geometric altitude of 22,000 ft has instrument readings of P = 880 lb/ft² and T = 430 °R. A) Find hp, hr, and ho to the nearest 1000 ft. B) If the aircraft were flying in a standard atmosphere, what would be the relationship among hp, ht, and ho?

show all steps in detail, units and formulas please.

Help with the questions: 1- Continuity tells us that whatever the volume of fluid in a pipe passing a particular point per second, the same volume must pass every other point in a second. The fluid is not accumulating or vanishing along the way. A) True B) False 2- When a fluid moves from a wider area of a pipe to a narrower one, its speed increases. A) True B) False 3- A fluid exerts a net upward force on any object it surrounds, called the buoyant force. A) True B) False

i need help with this question please

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.
