Cv is a for a constant volume, and there is therefore no work done in the expansion whereas as Cp accounts for the work done by the gas during its expansion, as well as the change in its internal energy. Thusly Cp is generally bigger than Cv.
Intuitively this would be very simple to work out yourself. We used to have to work this out ourselves back in my day, not just resort to cheap answers on the interweb.
According Cp if ur Crane is not contacting with any electrolyte like water, soil, means ther is no cp for atmospheric corrosion.
There are three statistical measures of "central tendency" - mean, median and mode. Combined, they give a picture of how close the data values cluster around a single "average" value. Normally, when someone talks of AVERAGE they are talking about the MEAN - where you add all the values and divide by the number of data points. But that value can be greatly affected by extreme values (e.g., the Mean of the following numbers: 3, 4, 4, 5, 4, 3, 27, 4, and 4 would be skewed by that one value that is not close to most of the others). The MODE of the numbers I gave, however, is the value that occurs most frequently - 4. The MEDIAN, the point where half the values are higher and half are lower, would also be 4. So, you see, the Central Tendency would be toward the value 4 and there is a strong Central tendency in this set of values. You could have a different set of numbers (e.g., 3, 27, 118, 11, 2, 963, 48) and while you could calculate an arithmetic mean, you could see that it wouldn't be too useful since there is no real Central Tendency of the data.
As the intensity of pressure increases with depth so for an inclined surface CP is bellow CG. Center of gravity : a point from which the weight of a body or system may be considered to act. In uniform gravity it is the same as the center of mass.
Reduced friction, smoother operation, more power delivered. A big disadvantage is that the slot in the yoke wears rapidly due to sliding friction.

Because Cp has two functions:- 1-To change the internal energy dU. 2-To do work dW in expanding the gas. Where as Cv has only one function of changing the internal energy of the gas..by awais
No, this relation is ONLY for ideal gases. The difference between Cp and Cv can be written more generally as T*(dP/dT)v*(dV/dT)p, where the lower case v and p represent the derivatives taken at constant volume and pressure, respectively. If you take these two derivatives using the ideal gas law (PV=nRT), then the result simplifies to Cp-Cv=R. However, solids and liquids do not follow the ideal gas law, and the difference between Cp and Cv is much smaller... negligible in many cases. For solids, Cp-Cv can be calculated using the isobaric expansivity, isothermal compressibility, and density of the material.

= 1 - qout/qin = 1 - cv(T4-T1)/(cv(Tx-T2)+cp(T3-Tx))
To find the atomicity of an ideal gas you can use γ = Cp/Cv.
Gasses have two specific heat capacities because the boundary conditions can affect the number by up to 60%. Therefore, a number is given to each boundary condition: isobaric (constant pressure) or isochoric (constant volume). In an ideal gas, they differ by the quantity R (the gas constant - the same one you use in the ideal gas law): Cp = Cv + R where Cp is the isobaric molar heat capacity (specific heat) and Cv is the isochoric molar heat capacity.
Cp-Cv is the relation of Mayer's formula. It can also be defined in words as the difference between two specific heat capacities.
(rho/potential_density) = (p/reference pressure)^(1/gamma) where gamma is the ratio of specific heats Cp/Cv = 1.40.
