A spherical tank is being designed to hold 7 moles of methane gas at a pressure of 8 bar and a temperature of 50oF. Determine the volume of the spherical tank to be used.
(a) Calculate the weight of methane in the tank in kg
(b) Find an expression for V in terms of m, R, T and P
(c) Calculate the value of V in ft^3
(d) What diameter spherical tank should be used in ft
A circular concrete pipe (n = 0.012) carries a discharge of 450 cfs with a slope of 0.008 and is designed to run no more than 60% full (by depth). What diameter pipe would you recommend
If this two-step process is replaced by a single isothermal expansion of the air from 800 K and 4 bar to some final pressure P, what is the value of P that make the work of the two processes the same
What is the velocity head expressed in atmospheres for a rapid filter operated at a surface loading rate of 475 m/d when the local porosity is 0.40?
A lagoon with volume 1200 m^3 has been receiving a steady flow of a conservative waste at a rate of 100m^3/day for a long enough time to assume that steady-state conditions apply
A 30-liter volume of gas at 25 degrees C contains 12 g of methane (CH4), 1 g of nitrogen (N2), and 15 g of carbon dioxide (CO2). Calculate (a) the moles of each gas present, (b) the partial pressure exerted by each gas, and (c) the total pressure ..
water flows at a velocity of 25 ft/s at a depth in a rectangular channel 16 feet wide. Determine the downstream depth necessary to form a hydraulic jump, the head loss through the jump and the horsepower dissipated in the jump.
A Pelton wheel, located at an elevation of 200.0 m, is used to extract power from a reservoir at an elevation of 800 m. A penstock 1500 m long and 0.8 m in diameter connects the reservoir with the nozzle of the Pelton wheel.
Assume that you have a constant diameter pipe that has no pumps or turbines connected to it.Prove that the fluid in the pipe will flow from a location with high piezometric pressure to one with low piezometric pressure.
What is the definition of a customer? What are some examples of internal and external customers? Is the measurement of customer satisfaction different for internal customers than for external customers?
Create a function called [polygon] that draws a polygon in a polar plot. Your function should have a single input paramter - the number of sides.
If the initial concentration of parathion in the runoff from the agricultural field is 3 ppb, the velocity of the river is 2.3 miles/day, how many days will the fish hatchery have to contain river water in holding tanks until the parathion concent..
