1 A pump with an 80% efficiency drives water up between two reservoirs through a piping system of total length L = 15 and circul

ar cross -section diameter d = 7 cm. The reservoirs are open to the atmosphere at an ambient temperature of 20 C. The difference in elevation between the free surface can be accounted for by the local loss coefficients Kentrance  Kexit 1.0, Kelbow 0.4. If the volumetric flow rate in the system Q = 10 Liter/s, and the surface roughness of the pipe is  = 0.15 mm, calculate:
(a) The average water flow velocity in the pipe.

Why is it important to compare the positive and negative test results with those of known compounds?
maks197457 [2]

It is important to compare the positive and negative test results with those of known compounds as positive results indicate the presence of that known compound and negative results indicate the absence of that compound which is used for reference.

<h3>What is qualitative analysis?</h3>

Qualitative chemical analysis is a method to determine the chemical composition of a sample.

There are two types of qualitative analysis:

  • Organic Qualitative analysis: It helps in determining the chemical bonds and functional groups in a sample
  • Inorganic qualitative analysis: It helps in determining the ions in the given sample

There are seven ways to analyze a sample qualitatively, which are

  • Change in color
  • Flame test
  • Distillation
  • Extraction
  • Precipitation
  • Chromatography
  • Spectroscopy

A reference compound is always used to which results are compared.

A Positive result indicates that the reference compound is present in the sample whereas a negative result indicates that the reference compound is absent in the given sample.
