The hero attending a funeral is safe behavior while the hero driving fast is riskier behavior
Answer:
Explanation:
![\dot{m_1}= 0.5kg/s](https://tex.z-dn.net/?f=%5Cdot%7Bm_1%7D%3D%200.5kg%2Fs)
from steam tables , at 250 kPa, and at
T₁ = 80⁰C ⇒ h₁ = 335.02 kJ/kg
T₂ = 20⁰C⇒ h₂ = 83.915 kJ/kg
T₃ = 42⁰C ⇒ h₃ = 175.90 kJ/kg
we know
![\dot{m_{in}}=\dot{m_{out}}](https://tex.z-dn.net/?f=%5Cdot%7Bm_%7Bin%7D%7D%3D%5Cdot%7Bm_%7Bout%7D%7D)
![\dot{m_{1}}+\dot{m_{2}}=\dot{m_{3}}](https://tex.z-dn.net/?f=%5Cdot%7Bm_%7B1%7D%7D%2B%5Cdot%7Bm_%7B2%7D%7D%3D%5Cdot%7Bm_%7B3%7D%7D)
according to energy balance equation
![\dot{m_{in}}h_{in}=\dot{m_{out}}h_{out}](https://tex.z-dn.net/?f=%5Cdot%7Bm_%7Bin%7D%7Dh_%7Bin%7D%3D%5Cdot%7Bm_%7Bout%7D%7Dh_%7Bout%7D)
![\dot{m_{1}}h_{1}+\dot{m_{2}}h_{2}=\dot{m_{3}}h_{3}](https://tex.z-dn.net/?f=%5Cdot%7Bm_%7B1%7D%7Dh_%7B1%7D%2B%5Cdot%7Bm_%7B2%7D%7Dh_%7B2%7D%3D%5Cdot%7Bm_%7B3%7D%7Dh_%7B3%7D)
