That due to the specific tasks that needs to be accomplished by each program to make an all encompassing program would be inefficient and full of bugs
Answer: Option D is not true of hydraulic valves. A hydraulic valve is a device that can change the opening degree of liquid flow path
Explanation:
The pilot check valve allows flow of liquid in one direction and blocks flow in the opposite direction
Answer:
![10.8\ \text{lb/ft^2}](https://tex.z-dn.net/?f=10.8%5C%20%5Ctext%7Blb%2Fft%5E2%7D)

Explanation:
= Velocity of car = 65 mph = ![65\times \dfrac{5280}{3600}=95.33\ \text{ft/s}](https://tex.z-dn.net/?f=65%5Ctimes%20%5Cdfrac%7B5280%7D%7B3600%7D%3D95.33%5C%20%5Ctext%7Bft%2Fs%7D)
= Density of air = ![0.00237\ \text{slug/ft}^3](https://tex.z-dn.net/?f=0.00237%5C%20%5Ctext%7Bslug%2Fft%7D%5E3)
![v_2=0](https://tex.z-dn.net/?f=v_2%3D0)
![P_1=0](https://tex.z-dn.net/?f=P_1%3D0)
![h_1=h_2](https://tex.z-dn.net/?f=h_1%3Dh_2)
From Bernoulli's law we have
![P_1+\dfrac{1}{2}\rho v_1^2+h_1=P_2+\dfrac{1}{2}\rho v_2^2+h_2\\\Rightarrow P_2=\dfrac{1}{2}\rho v_1^2\\\Rightarrow P_2=\dfrac{1}{2}\times 0.00237\times 95.33^2\\\Rightarrow P_2=10.8\ \text{lb/ft^2}](https://tex.z-dn.net/?f=P_1%2B%5Cdfrac%7B1%7D%7B2%7D%5Crho%20v_1%5E2%2Bh_1%3DP_2%2B%5Cdfrac%7B1%7D%7B2%7D%5Crho%20v_2%5E2%2Bh_2%5C%5C%5CRightarrow%20P_2%3D%5Cdfrac%7B1%7D%7B2%7D%5Crho%20v_1%5E2%5C%5C%5CRightarrow%20P_2%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%200.00237%5Ctimes%2095.33%5E2%5C%5C%5CRightarrow%20P_2%3D10.8%5C%20%5Ctext%7Blb%2Fft%5E2%7D)
The maximum pressure on the girl's hand is ![10.8\ \text{lb/ft^2}](https://tex.z-dn.net/?f=10.8%5C%20%5Ctext%7Blb%2Fft%5E2%7D)
Now
= 200 mph = ![200\times \dfrac{5280}{3600}=293.33\ \text{ft/s}](https://tex.z-dn.net/?f=200%5Ctimes%20%5Cdfrac%7B5280%7D%7B3600%7D%3D293.33%5C%20%5Ctext%7Bft%2Fs%7D)
![P_2=\dfrac{1}{2}\rho v_1^2\\\Rightarrow P_2=\dfrac{1}{2}\times 0.00237\times 293.33^2\\\Rightarrow P_2=101.96\ \text{lb/ft}^2](https://tex.z-dn.net/?f=P_2%3D%5Cdfrac%7B1%7D%7B2%7D%5Crho%20v_1%5E2%5C%5C%5CRightarrow%20P_2%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%200.00237%5Ctimes%20293.33%5E2%5C%5C%5CRightarrow%20P_2%3D101.96%5C%20%5Ctext%7Blb%2Fft%7D%5E2)
The maximum pressure on the girl's hand is ![101.96\ \text{lb/ft}^2](https://tex.z-dn.net/?f=101.96%5C%20%5Ctext%7Blb%2Fft%7D%5E2)
The odometer keeps running after you move beyond its upper limit, but the largest place values cannot be displayed due to overflow error.
