The initial head on an orifice was 2.74m and when the flow was terminated, the head was measured at 1.22m Under what constant head H would the same orifice discharge the same volume of water in the same time interval?

From a given prismatic reservoir the discharge from an orifice at the base would be 30 cu.ft. in “t” seconds if the head were constant at 16 ft. Under a falling head, starting at 25 ft, how much must it fall during the same time, “t”, so that the discharge during that time shall also be 35 cu. Ft., assuming the coefficient of discharge constant? What is the area of the vessel in square feet? If Cd = 0.85 and...

(a) A constant head permeability test was performed for the soil specimen. The sample length was 90 mm and sample diameter was 75 mm. The total head loss across the sample was measured to be 635 mm. The flow rate was measured and it took 278 seconds to fill up a 1-litre beaker. Estimate the coefficient of permeability (k), in m/s, based on results of the constant head test. (b) If a falling head test was conducted on the same...

What are the discharge and head values you would record at duty point for the selected pump? Pump Values Diameter of Pipe (D) = 150mm = 0.15m Length of Pipe (L) = 910m Friction Factor (lambda) = 0.05 Water Level (h) = 11m Area (A) = 0.01767m2

Darcy's law gives us the volume flow rate-volume per time (for example, cubic meters per day, m^3/day). Another way to express volume is on a per-unit-area basis. For example, if we have a 1-m^3 cube, we know its base is 1 m^2 the cross-sectional area of the cube-and its height is 1m. If we fill the cube with water, we can say we have 1m of water per unit area. Darcy's law can be rearranged to calculate the volume flow...

The number of coliform bacteria is reduced from an initial concentration of 2,000,000 per 100 ml to 400 per 100 ml in a long, narrow chlorination tank under a steady wastewater flow with a hydraulic detention time of 30 min. Assuming second-order kinetics and ideal plug flow, calculate the reaction rate constant. What would be the hydraulic detention time needed to produce the same effluent quality if you assumed perfectly mixed flow in the chlorination tank?

Order: NS​ 1,500 mL IV over 12 hours. The initial flow rate was correctly set at at 125​ mL/h. After 6 hours​ 1,200 mL remain to be infused. The infusion is behind schedule. Compute the new flow rate so that the infusion will finish on time. Note that flow rates may not be adjusted by more than​ 25% of the original rate. To what rate would you reset the flow​ rate, or would you contact the​ prescriber? A. 31​ mL/h...
