A storage tank contains water to a height of 25m. The air above the water  inside the tank has a gauge pressure of 4.5 atm

A box has a length of 1.3 cm, a width of 6.4 cm, and a height of 3.2 cm. Its mass is 9.8 kg. The box sits at rest on a horizontal floor.  What is the pressure of the box on the floor?

A bucket is filled with a combination of water (density 1000 kg/m3) and oil (density 700 kg/m3). These fluids do not mix (the oil will float on top of the water). If the layer of oil is 43 cm tall, what is the pressure at the interface between the oil and the water?

You come across an open container that is filled with two liquids. Since the two liquids have different densities, there is a distinct separation between them. Water, which has a density of pw = 1.00 x 10° kg/m², fills the lower portion of the container to a depth of 0.206 m. The fluid that is floating on top of the water is 0.314 m deep. If the absolute pressure on the bottom of the container is 1.049 × 10° Pa, what is the density, p1, of the unknown fluid? The acceleration due to gravity is g = 9.81 m/s² and atmospheric pressure is Po = 1.013 × 10° Pa. Pi = kg/m³

Water is flowing into a factory in a horizontal cylindrical pipe with a radius of 0.0193 m at ground level.This pipe is then connected to another horizontal cylindrical pipe with a radius of 0.0360 m on a floor of the factory that is h = 12.6 m higher.The connection is made with a vertical section of pipe and an expansion joint.Determine the volume flow rate that will keep the pressure in the two horizontal pipes the same. m3/s

A tube 5.00m long is inclined at an angle of 75° with the horizontal and is filled with water. What is the pressure at the bottom of the tube caused by the water if the tube is opened at the top?

A Venturi meter is a device for measuring the speed of a fluid within a pipe. The drawing shows a gas flowing at speed v2 through a horizontal section of pipe whose cross-sectional area is A2 = 0.0937 m2. The gas has a density of ρ = 1.30 kg/m3. The Venturi meter has a cross-sectional area of A1 = 0.0234 m2 and has been substituted for a section of the larger pipe. The pressure difference between the two sections is P2 - P1 = 149 Pa. Find (a) the speed v2 of the gas in the larger original pipe and (b) the volume flow rate Q of the gas.   I posted it just now and recieved the wrong answers so i'm asking again. The answers are not A) 1.87 and B) 0.157.

A 2.5 g latex balloon is filled with 2.4 g of helium. When filled, the balloon is a 30-cm-diameter sphere. When released, the balloon accelerates upward until it reaches a terminal speed. What is this speed? Assume an air density of 1.2 kg/m3.

A fish tank has dimensions 42 cm wide by 1.0 m long by 0.80 m high.If the filter should process all the water in the tank once every 3.0 h, what should the flow speed be in the 3.0-cm- diameter input tube for the filter?Express your answer to two significant figures and include the appropriate units.

A tank holds a large amount of water. A pipe is connected to the tank at the upper end and is open to the air at the lower end (see figure).The upper end of the pipe has a diameter of 17.0 cm. The lower end of the pipe has a diameter of 6.80 cm. The flow rate of the water in the pipe is 0.0500 .What is the speed of the water at the lower end of the pipe?
