Determine the missing properties and the phase descriptions in the following tables for water. Show your work. Also, indicate the relative positions in the P-v, T-v, and P-T diagrams.

T, °C P, kPa u, kJ/kg x
a 200 0.6
b 125 1600
c 1000 2950
d 74 500
e 850 0.0

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
