Answer:
Well its what makes a salad taste good.
the unit for volt is v
The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
Answer:
it can be calculated by measuring the final distance away from a point, and then subtracting the initial distance
Answer:
T2 = 662°c Q(in) = 911kj W(out) = 180kj
Explanation:
1. Firstly, we find the mass from the initial volume and specific volume from steam table A-5 for given pressure and state.
M = V(1)/a(1) = 0.6/0.7183(kg)
Where a(1) = specific volume
M = 0.835kg
The work is determined from the final pressure and the volume change that occurs when it is reached.
W = P2(V2 - V1)
W = P2V2
= 300×0.6kg = 180kg
Therefore, to get the final temperature and final pressure, the final temperature is determined fro steam table A-6 using interpolation.
T2 = T1* + T2*-T1*/a2*-a1* (a2-a1*)
T2 = 600 + 700-600/1.4958-1.34139 (1.43746-1.34139)
T2 = 662°c
2. The final internal energy can be determined in the same way just like the initial ones were done. From A-5 on steam table given the pressure
The heat Q(in) = ∆u + W(out)
= m(U2-U1) + W(out)
= 0.835(3412.3-2536.8)kj
+ 180
Q(in) = 911kj
