draw flowchart pls a$)$ Oxygen at $230K$ and $21.25$atm has a tabulated specific volume of $3\mathrm{.}87cm\frac{3}{g}$ and a specific

internal energy of $3450\frac{J}{m}oi.$ Calculate the specific enthalpy of Oxygen in this state, b$)$ Air is heated

from $25C$ to $150C$ prior to entering a reactor. The change in specific enthalpy associated with this

process is $4250\frac{J}{m}ol.$ The flow rate of air at the heater outlet is $6\mathrm{.}25m\frac{3}{m}in$ and the air pressure at

this point is $122$kPa absolute$.$ Calculate the heat reguirement in $kW,$ assuming ideal gas behavior and

that kinetic and potential energy changes from the heater inlet to the outlet are negligible.
