Heat capacity sample problems with solutions

WebHeat exchangers may also be fouled by the growth of algae in warm fluids. This type of fouling is called the biological fouling. Fouling represents additional resistance to heat transfer and causes the rate of heat transfer in a heat exchanger to decrease, and the pressure drop to increase.

WebSolution: Because q is zero in each part of this problem, †Esys is equal to wlab and †U is equal to w. We can use Eq. 3.1.4 with † v2 cm set equal to zero: †U †Esys D wlab w D mg†zcm or †Esys D †U Cmg†zcm. (a) The system is the marble. Solution: †U is zero, because the state of the system is unchanged. WebSolution: 1) the mass of intake air At the beginning of calculations, we must determine the amount of gas in the cylinder before the compression stroke. Using the ideal gas law, we can find the mass: pV = mRspecificT where: p is the absolute pressure of the gas m is the mass of the substance T is the absolute temperature V is the volume
