sedangkansaat temperatur sama atau lebih dari temperatur kritis Tc maka tekanan akan terusmenerus turun pada temperatur tetap isotermal dan quantity spesifik naik dan tidakmemotong padadaerah dua fasa gambar b. Pada gambar 3. 2 b terlihat garis KN dimulainya proses terlihat mulainya cekunganlebih kecil pada titik K kemudian dengan pemanasan menyebabkan cairan menguapmengakibatkan cekungan berkurang ke titik N Pada gambar 3. 3 terlihat garis J,K N,Q,C merupakan kurva uap. Proses diawali dari J,Kdengan pemanasan yang meningkat sampai dengan titik kritis vital point danberlanjut disepanjang garis volume spesifik yang konstan Vc. Vc adalah volumespesifik /molar yang konstan sepanjang garis setelah titik kritis. Thus within engineering comfort zone most engineering matlab americans will feel relaxed if all those features are addressed. Coal, gas, and oil are matlab fossil fuels guilty for most engineering matlab world’s electrical energy and effort demands. Coal, which is instantly accessible in most engineering matlab developing and built international, has been used as engineering top resource of fuel even in ancient human civilizations. It also found its use in historical steam engines at matlab dawn engineering matlab commercial revolution. Today, advances in technology have allowed coal to enhance living circumstances with its current role in assembly man’s fuel necessities. Coal has been used commonly in drive generation where higher know-how is hired to make sure that there’s engineering stability among ecology and economics in producing sustainable and low-cost energy.
