A gas undergoes a process in a piston–cylinder assembly during which the pressure-specific volume relation is pv1.1 = constant.

Sati [7]

Answer:

$\Delta u = 53.99 Btu/lbm$

Explanation:

given data:

$P_1 = 160 lbf/in^2 = 23040 lbf/ft^2$

$P_2 = 300 lbf/in^2 = 56160 lbf/ft^2$

$V_1 = 1ft^3$

Q = - 2.1 Btu

$PV^{1.1} = constant$

$P_1V_1^{1.1} = P_2V_2^{1.1}$

$V_2 = V_1 [\frac{P_1}{P_2}]^{1.1}$

$= 1 [\frac{23040}{56160}]^{\frac{1}{1.1}$

$= 0.44 ft^3$

work done during polytropic process

$w = \frac{P_2V_2 - P_1V_1}{1-n}$

$= \frac{56160 \times 0.4759 - 23040\times 1}{1 - 1.2}$

= -18442.1 ft lbf

we know 1 Btu = 778.169 ft. lbf, therefore

w = -23.6993 Btu

$Q = W + m\Delta u$

$-2.1 = - 23.6993 + 0.4 \Delta u$

$\Delta u = 53.99 Btu/lbm$

Why does the total amount of energy before and after<br> any energy transformations remain the same?

snow_tiger [21]

The Law of Conservation of Energy states that, in an isolated system, energy remains constant and can not be created or destroyed, only transferred from one form to another. This law was created by Julius Robert Mayer.

The wheels of a car have radius 12 in. and are rotating at 600 rpm. Find the speed of the car in mi/h.

guajiro [1.7K]

Answer:

21.4 mph

Explanation:

Circumference of tire in FEET = pi * d = pi * 1 ft = pi feet

pi feet x 600 rot/min * 60 min /hr * 1 mile / 5280 feet = 21.4 mph
