Given discharge is 450 m3/s, river width is 50 m at a depth of 6 m and bed slope of 0.0003, the sediment has a typical diameter of 0.01 m. Estimate the bedload transport using Shield and Einstein-Brown formula. 2. Annual precipitation measurements (Pi in cm) for M City, were given in Problem 1. Determine the magnitude of the 10-year precipitation depth if the data fit: the normal distribution. the Gumbel distribution. How many times was the P10 (normal) exceeded...

A factory disposes 1.1 m3/s of treated industrial wastewater into a river. The wastewater has an ultimate biochemical oxygen demand of 25 mg/L and dissolved oxygen of 2 mg/L. Just upstream of the wastewater outfall, the river has a flow rate of 10 m3/s, ultimate biochemical oxygen demand of 6 mg/L, and oxygen deficit of 2 mg/L. At the river temperature, the saturation concentration of dissolved oxygen is 9 mg/L. The deoxygenation coefficient is 0.19 d-1 and reaeration coefficient is...

An old storage tank of “46” m3 stores steam at 6000 kPa and 330 °C. A crack develops at the top wall of the tank and steam starts to leak out to the atmosphere. An engineer realizes the problem on time and stops the leak when the pressure inside the tank is below 4000 kPa. If the leak is assumed to be adiabatic and reversible, a) What is the final temperature of the steam remained in the tank? (10 points)...

A pump storage facility takes water from a river at night when demand is low and pumps it to a hilltop reservoir 500 ft above the river. The water is returned through turbines in the daytime to help meet peak demand. (a) For a single 30-inch pipe, 2,500 ft long and carrying 20,000 gaVmin, what pumping power is needed if the pump efficiency is 85 percent? The friction loss is estimated to be 15 ft of water. (b) How much...

If an object accelerates for infinite time, then it will in the end reach speed of light.

I have some question about relativistic features of objects which moves with speed of light. If an object accelerates for infinite time, then it will in the end reach speed of light. Then, to make it clear, assume a rocket with infinite power source (source is also assumed to be massless) that accelerates in space, or vacuum without any disturbance in its motion. Also assume that there is another rocket same as the one mentioned above and, in vacuum, it...
