A 40% pressure drop across an oil filter screen indicates that the
Homework Answers
Oil filters usually have an oil pressure relief valves which
will allow engine oil to continue blowing in the circumstances like
when the oil filter is clogged with aged oil.
This can lead to oil pressure dropping as the engine warms up
because it will require more oil on getting heated.
40% pressure drop indicates that there is certainly a fault in the system or the engine oil probably needs to be changed before its too late.

In a particular Millikan oil-drop apparatus, the plates are 2.25 cm apart. The oil used has a density of 0.830 g/cm3 , and the atomizer that sprays the oil drops produces drops of diameter 1.00×10−3 mm . A. What strength of electric field is needed to hold such a drop stationary against gravity if the drop contains five excess electrons? B. What should be the potential difference across the plates to produce this electric field? C. If another drop of...

Exercise 3 An oil well in the X Field is producing at a stabilized rate of 600 STB/day at a stabilized bottom-hole flowing pressure of 1800 psi. Analysis of the pressure buildup test data indicates that the pay zone is characterized by a permeability of 120 md and a uniform thickness of 25 ft. The well drains an area of approximately 40 acres. The following additional data is available: r.= 0.25 ft B. = 1.25 bbl/STB A = 40 acres...

3.1 Osmotic Cell Disruption Use the van’t Hoff relationship to estimate the osmotic pressure drop across the membrane of a cell undergoing rupture in a 0.01 M salt solution, assuming the internal salt concentration is 0.2 M and that all salts are fully dissociated. Would you call this a negligible, ordinary, or large pressure drop? Why?

In an oil-drop experiment a negatively charged oil drop has a mass of 3.0 x 10-15 kg and is held at rest between two parallel plates separated by a distance of 2.0 cm. The potential difference between the plates is 460 V. a) On the diagram below, show all the applied forces on the drop. Do not include the buoyant force of the air on the oil drop. b) What is the strength of the electric field between the plates?...
