An insulated 40 ft^3 rigid tank contains air at 50 psia and 580°R. A valve connected to the tank is now opened, and air is allow
Pachacha [2.7K]

Answer:

The answer is "\bold{W_{in} = 645.434573 \ Btu}".

Explanation:

Its air enthalpy is obtained only at a given temperature by A-17E.  

The solution from the carbon cycle is acquired:

\to \Delta U= W_{in}-m_{out}h_{out}=0\\\\\to W_{in} = (m_1 - m_2)h

           =\frac{Vh}{RT}(P_1- P_2)\\\\= \frac{40 \times 138.66}{0.3704\times 580}(50-25) Btu\\\\= \frac{5,546.4}{214.832}(25) Btu\\\\= 25.8173829(25) Btu\\\\ =645.434573 Btu

W_{in} = 645.434573 \ Btu

A 50kg block of nickel at 90°C is dropped into an insulated tank that contains 0.5 m3 of liquid water at 25°C. Determine the fol
Valentin [98]

Answer:

a).Control volume

b). C_{nickel} = 502.416 J/kg-K

c).  C_{water} = 4.187 kJ/kg-K

d). T_{2} = 87.91°C

Explanation:

a). It is a control volume system because mass is varying in the system.

b). Specific heat of nickel is C_{nickel} =   502.416 J/kg-K

c). Specific heat of water is  C_{water} = 4.187 kJ/kg-K

d).We know that

   net  energy transfer = change in internal energy

m_{nickel}\times c_{nickel}(T_{2}-T_{nickel})=m_{water}\times c_{water}(T_{2}-T_{water})

m_{nickel}\times c_{nickel}(T_{2}-T_{nickel})=(volume_{water}\times density_{water})\times c_{water}(T_{2}-T_{water})

50\times 502.416\times (T_{2}-90)=(0.5\times 1000)\times 4.187\times (T_{2}-25)

25120.8\times (T_{2}-90)=2093.5\times  (T_{2}-25)

T_{2} = 87.91°C
