Suppose your car gets stuck in a flooding area, and the water rises around you. Don't worry – the water doesn't rise high enough to pose any danger, but you'd like to be able to get out of the car so that you don't have to wait for the floodwaters to subside. The question is, how hard will you have to push in order to open the door? The diagram below shows the geometric information you need for the problem. 1265 mm 195 mm 825 mm 1. If the water rises to 150 mm above the bottom of the door, calculate the hydrostatic force on the door (using standard units). Show your work. 2. If you try to open this door, you would most likely push on the edge furthest from the hinges. Why? (Hint: look up the moment of a force) 3. Would it be possible for you to open this door? Assume that you push on the edge furthest from the hinges, and for the purposes of the moment that the hydrostatic force is located halfway between the hinges and the other edge. Justify your answer. 4. Find the maximum height of the water that would still allow you to open the door, using the same assumptions as above.

Solve completely and support your solution with diagrams or figures. The storage tank of a water tower is nearly spherical in shape with a radius of 30 ft. If the density of the water is 62.4 lb/ft3, what is the mass of water stored in the tower, in lb, when the tank is full? What is the weight, in lbf, of the water if the local acceleration of gravity is 32.1 ft/s2?
Velocity varies linearly with distance through the water nozzle shown below. Find the pressure gradient, dp/dx, halfway through the nozzle in psf/ft. Take the density of water at 62.4 lbm/ft3. Round off your answer to the nearest tens place. Indicate the numeric value only.
What horizontal and vertical forces are acting on a water tunnel like you see it in an aquarium and what force is exerted on the footers of the glass tunnel? Use reasonable numbers for your calculations. (make up values)
A gate rotates at point A and releases water when the water's depth, d, exceeds a certain value. The gate's width (perpendicular to the image) is b = 2.95 ft, the water's depth is d = 4.82 ft, and point A is located at h = 2.41 ft. a) What is F, the magnitude of the horizontal force exerted on the gate by the water? The water's specific weight is γw=62.4lb/ft3. b) What are Ax and Bx, the horizontal reaction forces at points A and B that act on the gate from Part A. c) What is dmax, the water's maximum depth before the pressure causes the gate from part A to open?
Figure Q5 shows a radial gate, where fluid of specific gravity (s.g.) of 0.437 is contained. If it is 30 m long (into the page), find the magnitude and direction of the resultant force acting on it. The radius to the gate is 3 m. 10 C - 104 degree
A tank, shaped like a cone has height 8 meters and base radius 3 meters long. It is placed so that the circular part is upward. It is full of water, and we have to pump it all out by a pipe that is always leveled at the surface of the water. Assume that a cubic meter of water weighs 10000 N, i.e. the density of water is 10000 N/m3. How much work does it require to pump all water out of the tank? Enter the exact value of your answer.
Imagine you are sitting in a Canoe with your friend in Lake Conroe north of Houston. There is a piece of rock inside the canoe. Your friend then gently throws the rock inside the lake. After the rock has completely sunk in the water, do you think the water level in the lake Conroe a) stays the same, b) decreases, c) increases (ever so slightly)? back up answer with calculations
An engineer is designing the runway for an airport. Of the planes that will use the airport, the lowest acceleration rate is likely to be 3 m/s2. The takeoff speed for this plane will be 65 m/s. Assuming this minimum acceleration, what is the minimum allowed length (in meters) for the runway?
In the second part of the lab you will observe a cart sliding down an inclined track. Suppose the track is 1.5 meters long (D in the diagram in the theory) and 30 cm tall at its end (Dh in the diagram). Calculate the acceleration of a frictionless cart rolling down this track.
Create an equation and explain how did you arrive at that equation.
Ms. MacLean draws the diagram below on the board. She uses the diagram to relate the positions of the Moon and Sun to their effect on Earth's tides for the class. Which correctly compares two positions of the Moon in the diagram as to how they relate to tides? A Both positions 1 and 3 result in higher high tides. B Both positions 1 and 3 result in lower high tides. C Both positions 2 and 4 result in higher high tides. D Both positions 3 and 4 result in lower high tides.
