The laboratory apparatus we used to measure hydrostatic forces is shown below.
a) Derive the formula for ''W'' as a function of ''h''.
b) Plot h versus W. Use the actual values that we used during the lab session for L, Y and b.
A 40 oF breeze of 10 miles per hour blows over the top of a round open-top water cooling tank which has a bulk temperature of 100 oF. What is the rate of energy in kW that enters into the air What type of heat transfer mechanism is employed in thi..
If arm OA rotates with a constant clockwise angular velocity of theta dot(first dirivatie)=1.5 rad/s. determine the force arm OA exerts on the smooth 4-lb cylinder B when theta=45 degrees.
A piece of corroded steel plate was found in a submerged ocean vessel. it was estimated that the original area of the plate was 62.5cm 2 and approximately 2.8k had corroded away during the submersion. Assuming a corrosion penetration rate of 5.1mm/yr..
An important dimensionless parameter concerned with very high-speed flow is Mach Number, defined as V/c, where V is the speed of the object such as airplane or projectile, and c is the speed of sound in the fluid surrounding the object.
Design a parshall flume to handle 24mgd in a 10ft wide channel at a downstream depth of 3 ft. If the channel floor is at elevation 65.7ft, what is the water elevation upstream of the flume
Determine the % error n in replacing the sine and the tangent of an angle by the value of the angle in radians for angle values 5,10,20 degrees. Explain the qualitative difference between the sine and tangent results.
Explain what is all about hydrated cement
A soil, 150mm x 150mm x 20mm high, is subjected to simple shear deformation. The normal force in the Z direction is 1 kN and the shear force is 0.5 kN. The displacements at the top of the soil in the X and Y directions are delta x = 1mm and delta z =..
Assume to just using coal as an electric energy source. Take efficency as %50 for average power plant.If the carbondioxide level is 400 ppm by volume now, what will be the carbondioxide level 10 years later
A number 10 (No. 10) steel rebar is tested in tension. By monitoring the load reading of the testing machine, it was found that the specimen yielded at a load of 41,600 lb and fractured at 48,300 lb.
A rod of steel is 20 m long at a temperature of 200C. find the free expansion of the rod when the temperature is raised to 65 0 C. Find the temperature stress produced
Determine the depth of a French drain (saturated depth) if the width is 3.0 feet, the effective permeability of the aggregate is 2000 ft/day, and the rate of discharge for 100 feet of trench is 1000 feet^3/day. The trench slope along the flow line is..
