A hydraulic jump is formed in a rectangular channel 6.5 ft wide.
The conjugate depths are 0.5 ft and 4.0 ft respectively. Calculate:
a. specific discharge, b. energy lost in the jump, c. critical
depth, minimum specific energy, d. Horsepower lost, e. Length of
the jump and f. Classify the Jump.
To combat antibiotic resistance, the Quality Improvement
Consortium recommends a throat swab to confirm strep throat before
a physician prescribes antibiotics to children under age 5. In a
random sample of 98 children who received antibiotics for throat
infections, 35 did not have a throat swab. At α = 0.05, is this a
statistically significant reduction over last year’s national rate
of 40 percent?

A venturi tube is measuring the flow of water; it has a main
diameter of 4.5 cm tapering down to a throat diameter of 1.1 cm .
If the pressure difference is measured to be 80 mm-Hg, what is the
velocity of the water?
why is neglecting to do a final rinse of the stirring
rod with poluceman into the beaker containing the accumulated
copper of error in the experiment. What would the effect of this
error be on your mass of copper? what would the effect of this
error be on the ratio of mol Cu or Mol Fe
plz i need the answer plz type the answer
i cannot read the hand writing
Throat swab from red inflamed throat – Streptococcus pyogenes,
Streptococcus pneumonia and Enterococcus facecalis Which plates are
you going to use to culture the material? Choose two and explain
use What is the ingredient in the selective plate? What is the
ingredient in the differential plate? What would you see if this
plate has growing on it? What antibiotic would you suggest (Use the
figure from Ch12 in the Cowan book)
Is there an observable trend or difference between all the
flowmeters readings (venturi, rotameter, and orifice) and the
system flow rate (obtained using magnetic or coriolis
flowmeters?
