Compute:

01100 - 10011

Assuming 2's complement representation. Verify the accuracy of the result:

• detect possible overflow
• compute the decimal values that are actually represented by the arguments and the result.

During a flow of 500 liters, the gage pressure is 68 kPa in the horizontal 300 mm supply line of a water turbine. A 41 kPa vacuum is measured at a 450 mm section of draft tube 2 m below the turbine. Assuming an efficiency of 85%,

a. Compute the total head extracted by the turbine.

b. Compute the output horsepower of the turbine.

c. Compute the input horsepower of the turbine.
