A 4-inch insulated arctic pipe is used for a construction camp. The lake source is 1500 meters away. The line is above ground on mud sills. Calculate the heat loss from the pipe if the outside ambient temperature is -40 deg F (minus 40). and the water coming out of the lake is at 1 deg C. Assume that the ID is 4-inches, OD is 4.5- inches and it s covered by 2-inches of urethane insulation. Use a k-factor of 34.9 BTU/hr-ft-degF for the pipe, 0.16 BTU-in/hr-ft2-degF for insulation, and an inside and outside convective film coefficients of 12.3 BTU/hr- ft2-deg F and 6.2 BTU/hr-ft2-deg F. Answer C 13.7 kW E 18.5 kW C 25.0kW C 28.5kW

2. A 20 cm long ram has its entire length engaged in a cylinder. The diameter of the ram is 10 cm and the gap between the ram and the cylinder is 1mm which is filled with SAE 30 oil at 40°C. The ram travels at 54. Find the frictional resistance(force) of the surfaces.
Two pipes A & B carries an oil of specific gravities 0.9 & 1.2 respectively. The center of the pipe A is 45 cm above the pipe B. The height of oil in right limb is 40 cm. Also, the mercury level difference is found in right limb as 90 cm. Find the pressure difference between these two pipes in kPa. Also find the pressure equivalent in water head in mm. The difference of pressure between two pipes (PA-PB) (Unit is in kPa) = Equivalent to Water head in mm =
