The Antoine Equation can be used to estimate vapor pressure at various temperatures for different substances using sets of empirically-derived constants. The equation can be written as: Where for water A = 8.07131, B = 1730.63, C = 233.426, T = temperature [°C], and P = vapor pressure [mmHg]. Note that with these constants the temperature and pressure must be provided in °C and mmHg, respectively. Using the Antoine Equation and the provided constants, what atmospheric pressure (provided in terms of % of standard atmospheric pressure) will permit water to boil at 75 °C?

A gas flows of from a station (a) with pressure of 20[bar] through a pipe with 0.4[m] diameter and4000 [m] length to a different station (b). The pressure at the exit (station (b)) is 2[bar]. The gasand the sounding temperature can be assumed to be 300 K. Assume that the flow is isothermal,k=1.4, and the average friction f=0.01. Calculate the Mach number at the entrance to pipe and theflow rate.

In order to fnd the specifc heat c of an unknown substance, you place 75 g of the substance in a 30 g copper calorimeter that contains 65 g of water, all initially at 20 °C. You then add 100 g of water at 80 °C, and measure the fnal temperature of the system to be 49 °C. Assuming no heat is lost to the environment, what is c? [Answer: c = 2200 J/kg. K] 즈
