- Read the question carefully and give me right solution according to the question. Before solve the question please understand the question. A cylinder having a diameter of 1.2 m and weighing 805 N floats in salt water (sg = 1.03) with its axis vertical. It is anchored at the bottom of the sea with a concrete block 0.57 m3 in volume and weighing 23.56 kN/m3 as shown. Determine the rise of tide, h, which will be required to lift the anchor from the bottom of the sea.A rectangular box is floated. Outer dimensions 2m by 10m and has 2m high sides and weighs 4.9N. It carries a load of 4.9N. It is launched in a pool of water with density 1 g/cm3. How much (in m) of the boat submerged (actual draft)? Provide the answer in appropriate precision (significant digits).Given: A vertical cylindrical tank is 10m high and 7m in diameter. It is two thirds full of water and is rotated uniformly about its axis until on the point of overflowing. Question: If it is rotated at a speed of 48 rpm. what is the pressure at the center bottom of the tank? Unit of the Correct Answer: kPaDecimal Places required in the final answer: 3
- Q5. A brass cube “R” inch on a side weighs (Rx10)lb.Hold this cube in equilibrium underwater by attaching light foam buoy to it. If the unit weight of foam is 4.5 lb/ft3, calculate the minimum required volume of the buoy? (where R is ) 32)?Compare and contrast the pros and cons of using water manometer in reading pressures instead of mercury manometers. Explain in a brief but meaningful way.A rectangular tank 3 m x 4 m is 5 m high with 2 orifices placed at a vertical distances of 0.5 m and 1m from the bottom respectively. Both orifices are 100 mm diameter with C=0.607. Determine the: show complete solution a. How long will it take to lower the water at tank by 2 m in seconds?b. How long will it take for the water surface to be at the same level as the upper orifice in seconds?

How many KN of lead weighing 110KN/m³ must be fastened to the outside bottom to make the cylinder float vertically with 1.5msubmerged in freshwater?
- 1.) What is the mass (lbm) of an object that has a base area of 4 inch2 which exerts a pressure of 25 psi? 2.) Determine the dynamic viscosity (Pa-sec) and kinematic viscosity (m2/s) of water with a specific weight of 9.81 kN/m3, if a Falling Sphere Viscosimeter test is conducted using an aluminum sphere that has a diameter of 10 mm and a specific weight of 28.06 kN/m3. The theoretical terminal velocity of the sphere is 0.650 m/s. Round off your answer to 3 decimal places. 3.) Given the water tank A in an orifice setup that transfers water to tank B, determine the theoretical and actual velocity and flow rate if the time it takes to fill up tank B is 20 sec. 4.) Given the computed velocities and flow rates in Question 3, determine the coefficient of contraction, velocity, and discharge. Assume the diameter of vena contracta to be 4mmø.From this figure, is the tank filling or emptying?This problem involves a cylinder falling inside a pipe thatis filled with oil, as depicted in the figure. The small space betweenthe cylinder and the pipe is lubricated with an oil film thathas viscosity . Derive a formula for the steady rate of descentof a cylinder with weight W, diameter d, and length sliding insidea vertical smooth pipe that has inside diameter D. Assumethat the cylinder is concentric with the pipe as it falls. Use thegeneral formula to find the rate of descent of a cylinder 100mm in diameter that slides inside a 100.5 mm pipe. The cylinderis 200 mm long and weighs 15 N. The lubricant is SAE20W oil at 10°C.
