You have a [x]-gallong water tank that weights [y] pounds when empty. With some water added to the tank, it now weighs [z] pounds. How many gallons of water are in the tank? Round to the nearest whole number. anyone know this answer?

Agas mixture consists of 8 kmol of h2 and 2 kmol of n2. determine the mass of each gas and the apparent gas constant of the mixture.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
