A 10 ft vessel contains a gas with an absolute pressure of 2102.893 kPa. An outside work is added to the system until the pressure was increased to 2656.568 kPa (gauge). The gas has a cp of 3.419 BTU/lb-R and k of 1.404. Prove that: a. Wn and du = 286,038.7 Ibr-ft; b. ds = 0.569 BTU/R (at an assumption of m = 1lb); c. dH = 516.443 BTU; and d. a 1.147 Ib of the gas is needed to completely fill up the vessel of the initial temperature is 40 deg F.

4. A 10 ft vessel contains a gas with an absolute pressure of 2102.893 kPa. An outside
work is added to the system until the pressure was increased to 2656.568 kPa (gauge).
The gas has a cp of 3.419 BTU/lb-R and k of 1.404. Prove that:
a. Wn and du = 286,038.7 Ibr-ft;
b. dS = 0.569 BTU/R (at an assumption of m = 1lb);
c. dH = 516.443 BTU; and
d. a 1.147 Ib of the gas is needed to completely fill up the vessel of the initial
temperature is 40 deg F.
