Water is contained in a piston-cylinder assembly undergoes four processes separately, all started from an initial state where th
e pressure is p1, the temperature is T1, and the specific volume is v1:
Process 1→2: Constant temperature (isothermal) to p2 = 2p1; Process 1→3: Constant specific volume to p3 = 2p1;
Process 1→4: Constant pressure (isobaric) to v4 = 2v1; Process 1→5: Constant temperature (isothermal) to v5 = 2v1.
Draw a p-v diagram and a T-v diagram for the water including the saturated liquid line and the saturated vapor line (dome).
The initial state (state 1) is at the saturated vapor state, note down state 2, 3, 4 and state 5 on both diagrams, and draw all processes (Process 1→2, 1→3, 1→4 and 1→5)

Answer:
a) 22.5number
b) 22.22 m length
Explanation:
Given data:
Bridge length = 500 m
width of bridge = 12 m
Maximum temperature = 40 degree C
minimum temperature = - 35 degree C
Maximum expansion can be determined as
where , \alpha is expansion coefficient degree C
SO,
number of minimum expansion joints is calculated as
b) length of each bridge
