Offshore in deep water, a wave gage measures the height and period of a train of waves to be 2m and 7.5 s respectively. The wave train propagates toward the shore in a normal direction without refracting and the nearshore bottom slope is 1:40. It passes the outer end of a pier located in water 4.5m deep. a) Determine the wavelength, celerity, group celerity, energy density, and power in deep water.
A 30mm pipe X 460 mm rectangular duct carries air. What size square conduit is needed to transport 4m cube per sec of water at a distance of 45m and head loss of of 1.08m.
Use input values of epsilon (B1), pipe radius (B2), and Reynolds number (B3) to estimate "f" and place these in the same cells . Display the final answer in a message box and round to five figures. Use a short cut key of Ctrl+g
The air pressure is 120 KPa, the air temperatuer is 28 degrees C, and the dew point is 20 degrees C. Calculate the corresponding vapor pressure (ea) and relative humidity (RH). Assume Atmospheric pressure is 101,000 Pa.
Water at 20ºC flows at a velocity of 2 m/s in a 200-mm diameter horizontal ductile-iron pipe. a) Estimate the friction factor in the pipe, and state whether the pipe is hydraulically smooth or rough.
If the column is subjected to an axial compressive force of 800 kN, determine the required diameter of each reinforcing steel bar so that one-third of the load is carried by the steel and two-thirds by the concrete. Assume Esteel= 200 GPa and Econ..
For some minerals color is a diagnostic property making identification rather easy. However, certain minerals can also occur in a wide variety of colors making color a poor tool for identification. List different colors for the mineral quartz lo..
Calculate the undrained shear strength at a depth of 120 ft below the mudline. Calculate the undrained shear strength at a depth of 120 ft below the mudline if the soil has an OCR of 2.5 .
The meter inlet and throat are connected by the two legs of a mercury manometer. Use the Bernoulli equation to describe how this manometer can be used to measure the flow rate through the meter.
Traction and Total Resistance, Would you please help me with the following question: A 90 tonne rear dump truck travels on an 8% grade loose gravel road.
How much differential settlement is causing the additional stress of 4,000 psi in girder that is rigudly attached to columns at either end of its 50-ft span. The moment of inertia of the beam is 15,000 in4, and it is a 24-in.-deep beam section.
The supplier says it would prefer to sell the company a 65% NaOH solution and the company says the water content is immaterial as long as the equivalent costs are the same including freight.
