One mole of an ideal gas, initially at 30 [°C] and 1 [bar], is changed to 130 [°C] and 10 [bar] by two different mechanically reversible processes: • The gas is first heated at constant volume until its temperature is 130 [°C], then it is compressed isothermallyuntil its pressure is 10 [bar].• The gas is first compressed adiabatically; then it is heated isobarically to 130 [°C] and 10 [bar]. Calculate Q, W, ΔU, and ΔH in [J] for each case. Take Cp = 5/2R and Cv = 3/2R.
In an effort to modernize the United States interstate system, the Department of Transportation proposes to change speed limits from miles per hour to "flashes." A flash is equal to 10 feet per second [ft/s]. On a car speedometer, what will the new range be in units of "flashes" if the old scale was set from 0 to 160 miles per hour [mi/h or mph]?

7. When you work for a company that studies the performance of car engines, you are tasked with accurately measuring the amount of air intake by car engines. A gas flow meter was introduced from the United States to measure the amount of air. This flow meter measures the flow rate using the pressure difference. Looking at the instruction manual of this flow meter, the following equations were found for the pressure difference head and volume flow [unit, volume/time]. ▷ Volumetric Flow Rate[ft°/min]: =(55.3658* DP-0.143168* DP^ 2)) However, DP is the head (water height) of the manometer, and the unit is inch to be. In the above equation, if you insert DP[inch], the air volume flow rate can be calculated and the unit of the volume flow rate is ft/min. Complex unit conversion is included in the constant in front of DP, so you don't need to worry about it. Before the experiment to measure the amount of air inhaled into the engine, the current atmospheric pressure and temperature were…
