Estimating gas mileage: An example of order-of-magnitude physics
نویسنده
چکیده
I discuss how to estimate the gas mileage of a car. This discussion, which covers air resistance and Reynolds numbers, describes one way to introduce dimensional analysis and orderof-magnitude physics into introductory physics (if only the syllabus would allow it). It is part teacher’s guide and part textbook chapter – I hope not the worst parts of each.

Canonical thermostatics of ideal gas in the frame work of generalized uncertainty principle
The statistical consequences of minimal length supposition are investigated for a canonical ensemble of ideal gas. These effects are encoded in the so-called Generalized Uncertainty Principle (GUP) of the second order. In the frame work of the considered GUP scenario, a unique partition function is obtained by using of two different methods of quantum and classical approaches. It should be noti...
متن کاملCoupling Geomechanics and Transport in Naturally Fractured Reservoirs
Large amounts of hydrocarbon reserves are trapped in naturally fractured reservoirs which arechallenging in terms of accurate recovery prediction because of their joint fabric complexity andlithological heterogeneity. Canada, for example, has over 400 billion barrels of crude oil in fracturedcarbonates in Alberta, most of this being bitumen of viscosity greater than 106 cP in the GrosmontFormat...
متن کاملA New Approach for Finding an Optimal Solution for Grey Transportation Problem
In ordinary transportation problems, it is always supposed that the mileage from every source to every destination is a definite number. But in special conditions, such as transporting emergency materials when natural calamity occurs or transporting military supplies during wartime, carrying network may be destroyed, mileage from some sources to some destinations are no longer definite. It is u...
متن کاملA Fire Ignition Model and Its Application for Estimating Loss due to Damage of the Urban Gas Network in an Earthquake
Damage of the urban gas network due to an earthquake can cause much loss including fire-induced loss to infrastructure and loss due to interruption of gas service and repairing or replacing of network elements. In this paper, a new fire ignition model is proposed and applied to a conventional semi-probabilistic model for estimating various losses due to damage of an urban gas network in an eart...
متن کاملEstimating the Radiation-Induced Cancer Risks in Pediatric Computed Tomography
Introduction One of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. Therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...
