(a) A hydraulic jump occurs in an rectangular channel 2.3 m wide when the discharge is 2.5 m^3/s. If the upstream depth is 0.25 m calculate the depth downstream of the jump and the energy loss in the jump.
(b) A wide alluvial stream carries water with a mean depth of 1 m and slope of 0.0005. The mean diameter of the bed material is 0.5 m with a density of 2650 kg/m^3. Examine the stability of the bed.
State the basic difference between the general method of slices and the bishop method of slices. b.)State the basic difference between the bishop and fellenius method of slices
Determine the factors of safety against sliding and against overturning, and also the soil pressure at the heel and toe. Assume hydrostatic uplift varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe. consider 1m l..
An open vat in a food processing plant contains 400L of water at 20 degrees C and atmospheric pressure. If the water is heated to 80 degrees C, what will be the percentage change in its volume? If the vat has a diameter of 3m
Energy transfer in mechanical systems, A wheel is 800mm in diamiter and has a mass of 1000kg. on a horizontal surface without skidding, the vehicle accelerates uniformly at 0.5m/s^2 for 5 seconds.
The mass flow rate of steam into a steam turbine is 5 kg/s . The turbine has a heat loss of 5 kj/s. if the velocity of the refrigerant is to be limited to 2 m/s, what is the minumum allowable pipe diamter
A solution of HOCl is prepared in water by adding 15 mg HOCl to a volumetric flask, and adding water to the 1.0 L mark. The final pH is measured to be 7.0. What are the concentrations of HOCl and OCl
A liquid of 80 mole percent propane and 20 mole percent n-pentane is to be diluted with methane. Will all mixtures of the liquid and methane be single phase at 160 F and 500 psia
A non-reactive chloride solution is continuously discharged into an aquifer. The concentration at the discharge location is 800 mg/L. Determine the maximum concentration of chlorides to be observed at an observation well 30 m downstream of the disc..
Three prismatic bars, two of material A and one of material B, transmit a tensile load P. The two outer bars (material A) are identical. The cross-sectional area of the middle bar (material B) is 50% larger than the cross-sectional area of one of ..
the turbopump unit in the engine nominally operates at 7000 rpm, and a result of design issue, the actual thrust provided by the engine oscillates harmonically with an amplitude of 10 KN at the same rotational frequency as the turbopump unit.
The pump graphs are given to us, and I'm asked to determine possible lengths and diameters of the pipe to meet two requirments. The system can have multiple outputs in order to satisfy the needs, but they must be occuring at the same time.
A solution contains 300 mg/L of acetic acid. Determine the pH of the solution if an equivalent amount of sodium hydroxide (NaOH) is added to it. Determine the concentration of NaOH required (in mg/L).
