Air enters an adiabatic compressor through 0:5m2 opening and exhausts through a 0:2m2 opening. The inlet conditions of air are 2

gladu [14]

Answer:

i) 43.55 kg/s

ii) 40 m/s

iii) -199.32 KW

Explanation:

To resolve the above question we have to make some assumptions :

mass flow through the system is constant
The only interactions that are between the system and the surrounding are work and heat
The fluid is uniform

i) first we have to determine the mass flow rate of the air

M = $(\frac{P1}{RT1} )A1v1$

= $( \frac{200}{0.287*325} ) 0.5 * V1$ ---------- (1) hence M = 43.55 kg/s

ii) using this relationship : A1V1 = A2V2 hence V1 = (0.2/0.5) * 100 = 40m/s ( inlet velocity )

input this value into equation 1

iii) Next we will determine the power required to run compressor

attached below

power required = -199.32 KW ( this value indicates that there is power supplied )

An automobile having a mass of 1100 kg initially moves along a level highway at 120 km/h relative to the highway. It then climbs

soldier1979 [14.2K]

Answer:

$-6111.11\ \text{kJ}$

$863.28\ \text{kJ}$

Explanation:

m = Mass of automobile = 1100 kg

v = Velocity of car = 120 km/h = $\dfrac{120}{3.6}\ \text{m/s}$

h = Height of hill = 80 m

g = Acceleration due to gravity = $9.81\ \text{m/s}^2$

Change in kinetic energy

$KE=\dfrac{1}{2}m(u^2-v^2)\\\Rightarrow KE=\dfrac{1}{2}\times 1100\times (0-(\dfrac{120}{3.6})^2)\\\Rightarrow KE=-611111.11\ \text{J}$

Change in kinetic energy is $-6111.11\ \text{kJ}$

Change in potential energy is given by

$PE=mgh\\\Rightarrow PE=1100\times 9.81\times 80\\\Rightarrow PE=863280\ \text{J}$

The change in potential energy is $863.28\ \text{kJ}$ .
