engineering recuitment BHEL Engineer Trainee Mock Test 2025 Heat Transfer Heat Exchanger Heat Exchanger Analysis
Two fluid heat exchanger has inlet and outlet temperature of 65°C and 40°C for the hot fluid and 15°C and 30°C for the cold fluid. Find out whether it it counter flow or parallel flow and also calculate the effectiveness of heat exchanger.
1
Counter flow with effectiveness ϵ = 0.7
2
Parallel flow with effectiveness ϵ = 0.5
3
Parallel flow with effectiveness ϵ = 0.3
4
Counter flow with effectiveness ϵ = 0.4
