Water flows steadily through a horizontal nozzle. The nozzle inlet diameter is 6 in. At the nozzle outlet, where the pressure is atmospheric, the diameter is 2 in. Determine the pressure head at the nozzle inlet to produce a water jet velocity of 40 ft/s. Neglect the friction loss and assume incompressible flow.
Air can be assumed as a di-atomic ideal gas. Find the final temperature and the amount of work ( in kW) required for air compression at a rate of 100 mol/s , from an initial condition of 1 bar an 25 C to 10 bar; for the following ways:
A water tank has a height of 120m, and its area of cross-section is 2000m. Water is released from the tank and the water level drops by 1 meter every minute. Find the rate of change in volume.
Using the USLE, estimate the annual erosion from a 100 ha. forested watershed assuming the following: R =112 tonnes/ha/year. The forest is in fair condition with 40% cover; Average slope is 3%; The soils are clay loam in hydrologic group C.
At a specified point on a highway, vehicles are known to arrive according to a Poisson process. Vehicles are counted in 20-second intervals, and vehicle counts are taken in 120 of these time intervals.
Measurements indicate that to cause this flow the force acting on the contents of the control volume is 40i lb. Determine the net rate of flow of linear momentum through the control surface.
If the engine is mounted solidly on a rigid foundation, what is the alternating force amplitude transmitted? Assume the connection rod to be of infinite length.
My question is regarding UVA levels in raw and treated drinking water with regard to TOC and DOC removal. Is there a jar test procedure that incorporates the UVA values of the various stages of treatment and is there a document you could refer me ..
Working a problem where there are two one-story buildings of different heights next to each other. Earthquake imparts a base motion z(t) that is a cosine function. I'm given a shape function for a column of height L when deriving the EOM for each ..
Due to a crash at a railroad crossing, an overpass is to be constructed on an existing level highway. the existing highway has a design speed of 50 mi/h.
Jack Flubber, who owns sons of Flubber Construction Co. and runs it as a proprietorships had gross profit last year of $ 80000. His personal and family expenses are $ 52000 and he has $ 7000 in exemptions and deductions.
On a flexible pavement with a 3 inch hot mix asphalt (HMA) wearing surface, a 6 inch soil cement base and an 8 inch crushed stone subbase, which truck will cause more pavement damage?(Suppose drainage coefficients are 1.0).
What superelevation rate would you recommend for a roadway with a design speed of 100 km/hr and a radius of curvature of 500 m? Assume f = 0.11.
