Air flows steadily along a streamline from point (1) to point (2) with negligible viscouseffects. The following conditions are measured: At point (1) z1 = 2 m and P1 = 0 N/m2; at point (2)z2 = 10 m, P2 = 20 N/m2, and v2 = 0 m/s. Based on this information, what condition exists at point(2) and what type of streamline is this? Determine the velocity at point (1) in m/s. The specificweight of the air is 12.1 N/m3
Using the Hazen-Williams nomograph determine the following: a. The head loss as 5.6 liters/s of water flows through a 24.38 m length of 64 mm cast iron watermain pipe. b. The diameter of cast iron pipe that can carry 19 liters/s over a length of 366 m with no morethan a 3 m head loss. c. Compare the head loss that would result from the flow of 6.5 liters/s of water through 305 m ofcast iron pipe for 50 mm and 75 mm diameter pipe sizes.

HELP ME
Can you help me solve this question please? Thank you Salt lake has no outlet i.e., the inlet flow is completely balanced by evaporation. Lake has a volume of 2.5 x 1011 m3 and the concentration of salt in the lake is 52 g/L. Inlet stream to the lake has a concentration of 0.18 g/L and is flowing at a rate of 3.7 x 109 m3/yr. Lake initially had a concentration of 0.18 g/L and the outflow abruptly stopped, how long ago did that occur?
Note: Kindly provide a solution pls. The answer is already provided. Thank you! A horizontal cylindrical tank with diameter 0.61 m. and 3.44 m. long is filled with water to a depth of 0.45 m. Find the depth (in meters) of the water if the tank is in its upright position. Round off to three decimal places.
A test setup is shown. A cylindrical mold of 4 inches in diameter is filled to a height H1 = 0.2 ft., with silt whose coefficient of permeability K1 = 3.8 x 10 3 ft/min. A second coaxial mold is placed on the top of the first mold whose inside diameter is d = 1.5 inches and whose %3D height is 0.30 ft. Its Thickness is negligible. The inside of this second mold is filled with the same silt, but the annular ring outside the small tube and the outer tube is filled with sand whose coefficient of permeability is K2 = 7.5 x 104 ft/min. The test set up is a permeability of constant head. Water is placed in the mold and maintained at a level h = 1.5 ft. above the level of the outlet. It maybe considered that altogether, the system consists of a fictitious soil of thickness H= H1 + H2 = 0.5 and the coefficient of permeability Kr. Find the volume of water which percolate after 30 min in cubic ft.
There is a water supply well in an unconfined sand aquifer in Cape Cod near the shore. It has a screened section that extends from 25 to 45 feet below sea level. Without pumping, the water level in the well is 7.0 feet above sea level. The well was pumped at a steady discharge, and by the end of one week the water level was 1.0 foot above sea level. The water pumped during the week was consistently fresh with no significant change in salinity. Density of seawater is 1.025 g/cm3. Density of freshwater is 1.000 g/cm3 a) sketch the problem and estimate the level of the saltwater interface at the location of the well before and after the week of pumping. b) proceed with the calculation as if the conditions related to the Ghyben-Herzberg equation apply. c) Using the equation above, does the problem violate any of the following and if so why: The interface between the fresh and saltwater is sharp with no mixing, There is no resistance to vertical flow in the saltwater or the freshwater…
