A cylindrical pressure tank has internal dimensions of 14.0 inches diameter, and 36 inches length from end to end. Max. recommended pressure at 70degF is 200 PSI. The cylinder has a safety relief valve which is set at 250 PSI. Determine the following:
1) Inside volume of the pressure tank in ft^3
2) Specific volume of the tank at 70degF and 200 PSI
3) The mass of the air in the tank from question # 2
4) The tank pressure if 3.5 lbm of air is inserted into the tank at 70degF
The compound interest formula is F=P(1+i)n where F is the total amount due, P is the initial cost or amount of money, i is the interest rate, and n is the number of periods interest is computed. 1.A student purchases a $1400 laptop computer for sc..
