Two insulated tanks, \(A\) and \(B\), are connected by a valve. Tank \(A\) has a volume of \(0.70 \mathrm{~m}^{3}\) and contains steam at \(1.5 \mathrm{bar}, 200^{\circ} \mathrm{C}\). Tank \(B\) has a volume of \(0.35 \mathrm{~m}^{3}\) and contains steam at 6 bar with a dryness fraction of 0.90. The valve is then opened and the two tanks come to a uniform State. If there is no heat transfer during the process find the final pressure and the entropy change of universe.
