The flow rate of liquid metal into the downsprue of a mold = 0.7 L/sec. The cross-sectional area at the top of the sprue = 750 m
katrin [286]

Answer:

367.43 mm²

Explanation:

Given:

Flow rate, Q = 0.7 L/s

1000 L = 1 m³ = 10⁹ mm³

thus,

1 L = 10⁶ mm³

Therefore,

Q = 0.7 × 10⁶ mm³/s

Cross-sectional area at the top of the sprue = 750 mm²

Length of the sprue = 185 mm

Now,

Velocity = \sqrt{2gh}

where,  g is the acceleration due to gravity = 9.81 m/s²

h is the height through which flow is taking place = 185 mm = 0.185

thus,

Velocity = \sqrt{2\times9.81\times0.185}

or

velocity = 1.9051 m/s = 1905.1 mm/s

Also,

Q = Area × Velocity

thus,

0.7 × 10⁶ = Area × 1905.1

or

Area = 367.43 mm²

All of the following are advantages of using a pressure transducer rather than a vacuum gauge EXCEPT:
Artist 52 [7]

Question:

All of the following are advantages of using a pressure transducer rather than a vacuum gauge EXCEPT:

A. greater accuracy.  

B. easier identification of the cylinder.

C. measuring higher pressures.

D. ability to see the levels graphically

Answer:

The correct answer is D) ability to see the levels graphically

Explanation:

The above question derives from the Rudiments of Automotive Technology.

The function of the pressure transducer is to enable the diagnostic who is testing the engine vacuum to detect the cylinder with a faulty vacuum.

The pressure transducer does allow its user to see the vacuum graphically NOT  the levels.

Cheers.
