Irina-Kira [14]

Answer:

n=76\%

Explanation:

From the question we are told that:

Temperature T=50 \textdegree C

Intake Pressure P=1.5MPa

Exit Pressure P=15MPa

Work W=18kJ

Therefore

From Table

V_f=1.01*10^{-4}

Generally the equation for isentropic Work is mathematically given by

W_{iso}=V(P_2-P_1)

W_{iso}=1.01*10^{-4}(15-1.5)

W_{iso}=13.622

Since

Efficiency n

n=\frac{W_{iso}}{W}

n=\frac{W_{iso}}{18}

n=0.76

Therefore

n=76\%

During a baseball game, a batter hits a popup to a fielder a distance d m away. the acceleration of gravity is 9.8 m/s 2 . if th
s344n2d4d5 [400]

solution:

acceleration = 9.8m/s^2 \\
t = 6.3s \\
Initial velocity (vi) = 0m/s \\  vf = at + vi\\  vf = (9.8m/s^2)(6.3s) + 0m/s \\
vf = 61.74m/s \\
if you're asking for final velocity \\  
d = Vit + 1/2at^2 \\
d = (0m/s)(6.3s) + 1/2(9.8m/s^2)(6.3s)^2\\  d = 1/2(9.8m/s^2)(39.69s^2)  d = 194.481m
