Steam at an initial enthalpy of 100 kJ/kg and inlet velocity

Home » Thermodynamics » Thermodynamics Miscellaneous » Question

Steam at an initial enthalpy of 100 kJ/kg and inlet velocity of 100 m/s, enters an insulated horizontal nozzle. It leaves the nozzle at 200 m/s. The exit enthalpy (in kJ/kg) is ________

1. 85 × 10² J/Kg
2. 65 × 10³ J/Kg
3. 85 × 10³ J/Kg
4. 95 × 10³ J/Kg

Correct Option: C

h₁ = 100 KJ/Kg
V₁ = 100 m/s

h₁ +	V²₁	h₂ +	V²₂
	2		2

100 × 10³ +	(100)²	h₂ +	(200)²
	2		2

h₂ = 85 × 10³ J/Kg
