Methanol is withdrawn from a 6m3 storage tank with a flow rate which increase linearly with time. While the withdrawn process is continue at any time the amount of methanol in the tank is 700kg and the withdrawn flow rate is 700kg/h. After 5 hours, the withdrawn flow rate increase to 1000kg/h. Methanol is fed to the tank with a flow rate of 1200kg/h to complete the reduced amount. Calculate the amount of methanol in the tank after 4 hours (at the end of 4 hours). (Methanol density =792kg/m3 ) Sectiiniz cevabin isaretlendiini gorene kadar bekleyiniz. 1740kg 1520kg 2220kg 1420kg
