Explanation:

Step1: Identify gauge scale pattern

The outer scale (1-26) maps to inner PSI: each outer mark increments by 10 PSI, with small ticks adding 2 PSI per tick between major marks.

Step2: Match each outer number to PSI

1: $0 + 2 = 2$
2: $0 + 4 = 4$
3: $0 + 6 = 6$
4: $0 + 8 = 8$
5: $10$
6: $10 + 2 = 12$
7: $10 + 4 = 14$
8: $10 + 6 = 16$
9: $10 + 8 = 18$
10: $20$
11: $20 + 2 = 22$
12: $20 + 4 = 24$
13: $20 + 6 = 26$
14: $20 + 8 = 28$
15: $30$
16: $30 + 2 = 32$
17: $30 + 4 = 34$
18: $30 + 6 = 36$
19: $30 + 8 = 38$
20: $40$
21: $40 + 2 = 42$
22: $40 + 4 = 44$
23: $40 + 6 = 46$
24: $40 + 8 = 48$
25: $50$
26: $50 + 2 = 52$
