- A point in a water pipe line, velocity is 3.5m/s, the pressure reading is 20 kPa and the elevation is 20m.What is the energy head in meters at that point assuming that the reference datum is @ elevation 5m. *1. If the work done 10000 cal, and the initial pressure 100 atm, when the ideal gas | expand isothermally and reversibly from the initial l volume (V1) to the final volume (10 V1), R = 1.987 cal/mole.K. ~ (A) calculate V1. (B) If there are - 2 moles from ideal gas what is the temperature.What is the steam temperature of ultra-supercritical coal fired plant?

Calculate the heat flow and stating whether it is supplied or rejected and sketch the process on a T-s diagram. Answer = -135 kJ/kgA wire 100 meter long at 20 °C has a linear temperature coefficient of 2 * 10-51. The wire is heated and expands to a length of 100.01 m. What is the final temperature?
- A steel tape with a coefficient of thermal expansion of 0.0000116/°C is known to be 50 m long at 20°C. The tape was used to measure a line that is 642.90 m long when the temperature was 35ºC. a) Calculate the temperature correction per tape length. b) Calculate the correction for the measured line. c) Calculate the correct length of the measured line.Convert a pressure head of 10 m water column to kerosene of specific gravity equal to 0.8 and to Carbon tetrachloride of specific gravity 1.6A line was measured to be 412 m using a 30-m tape, which is of standard length at a temperature of 20 deg.C. During measurement, the temperature was 52 deg.C. If the coefficient of thermal expansion of the tape material is 0.0000116 m/m deg.C, calculate the correct length of the line.
- What is the steam temperature of supercritical coal fired plant?A 50 meter steel tape was used in laying out a distance of 550.55 m. The tape was standardized at 20 Deg Celcius and during the activity the mean temperature observe was 15 Deg Celcius. Determine the correct length to be laid out using the erroneous steel tape. Assume the coeffucuent of linear expansion of the tape to be equal 0.0000116 per 1 Deg Celcius.A steel tape with a coefficient of linear expansion of 0.0000116/oC is know to be 50m long at 20oC. The tape was used to measure a line which was found to be 532.28 meters long when the temperature was 35oC. Determine the following:a) Temperature correction per tape length.b) Temperature correction for the measured line.c) Correct length of the line.
