![### Required information
#### Problem 09.014 - 3-Step Air-Standard Cycle with Variable Specific Heats - DEPENDENT MULTI-PART PROBLEM - ASSIGN ALL PARTS
An air-standard cycle with variable specific heats is executed in a closed system with 0.0025 kg of air and consists of the following three processes:
1. **1–2 v**: Constant heat addition from 95 kPa and 17°C to 380 kPa
2. **2–3**: Isentropic expansion to 95 kPa
3. **3–1 P**: Constant heat rejection to initial state
Use data from tables.

### Problem 09.014.c - Cycle Efficiency for Variable Heat Capacity Air-Standard Cycle
Determine the thermal efficiency.
The thermal efficiency is [_____] %.
**Explanation**: This problem involves calculating the thermal efficiency of a 3-step air-standard cycle where specific heats can vary. It includes a process of constant heat addition, an isentropic expansion, and constant heat rejection back to the initial state. Data needed for calculations should be referred to from standard tables. The goal is to find the percentage efficiency of the cycle.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8edd889e-338a-4275-872c-5b2b400b4e22%2F60abe1bf-9d0a-4a59-84ac-bdab9f673a2c%2Ff5mnq7u_processed.png&w=3840&q=75)
