Refer to Figure P22.14 and the data provided with the figure. The compressor (C-101) exhausts to \(101 \mathrm{kPa}\). Tank TK-102 is controlled to be always \(101 \mathrm{kPa}\). Assume all flows are turbulent.

a. If the valve is closed, the flowrate from the compressor exhaust (Stream 7) is \(100 \mathrm{Mg} / \mathrm{h}\). What is the pressure in the storage tank (TK-101)?

b. If the pressure of TK-101 is kept constant at the pressure calculated in Part (a), what is the maximum flowrate of liquid (Stream 2) when the valve is wide open (i.e., no pressure drop across the valve)?

Figure 22.14

c. What is the flowrate of the compressor exhaust (Stream 7) when the valve is wide open? C-101 compressor curve:

\[
\frac{P_{\text {out }}}{P_{\text {in }}}=4.015+5.264 \times 10^{-3} \dot{m}-1.838 \times 10^{-4} \dot{m}^{2}
\]
P-101 pump curve:
\[
\Delta P=500+4.662 \dot{m}-1.805 \dot{m}^{2}
\]
where \(P\) is in \(\mathrm{kPa}\) and \(m\) is in \(\mathrm{Mg} / \mathrm{h}\).
