From table 8.3: Global valve - k= 10 Short-radius elbow - k= 0.9
A steel pipe will be installed and extends almost from one wall to another. The walls are 62.2 m apart. The pipe has a steel elbow at each end, and the design length of the pipe plus elbows is 61.5 m at 24.3 ºC. A clearance of 210 mm has to be left at either end of the pipe, for bracing to the wall. If the pipe is to carry steam at 375 ºC. (a) will it fit? (b) At what temperature will it just fit? 404 ºC

plzzzz help me nowww What is the minimum Block mass (kg) that is required to open the gate A-B? The density of water is 1000 kg/m3 and the density of the block is 8000 kg/m3. The specific gravity of oil is 0.9. The depth of the gate is not required. The external force that effects the gate at point A is Fe=3000 N, while the hydrostatic force Fh=9313.8 N
Factor of safety,F.S.=2.0
Find the heat load for an upstairs 14-foot by 12-foot bedroom that is not onthe corner of the house. The outside wall, the 14-foot wall, has 31⁄2 inches ofinsulation. The walls are 8 feet high, and there are two single pane windowsin that outside wall that are 4 feet 5 inches high by 3 feet wide. The ceilinghas insulation 6 inches thick. The house has a design temperature differenceof 70°F.
Sir please for fluid mech
A local ventilation system (a hood and duct system) is used to remove air and contaminants from a pharmaceutical lab. The inner diameter (ID) of the duct is D = 150 mm, its average roughness is 0.15 mm, and its total length is L = 24.5 m. There are three elbows along the duct, each with a minor loss coefficient of 0.21. Literature from the hood manufacturer lists the hood entry loss coefficient as 3.3 based on duct velocity. When the damper is fully open, its loss coefficient is 1.8. The minor loss coefficient through the 90° tee is 0.36. Finally, a one-way valve is installed to prevent contaminants from a second hood from flowing “backward” into the room. The minor loss coefficient of the (open) one-way valve is 6.6. The performance data of the fan fit a parabolic curve of the form Havailable = H0 − aV.2 , where shutoff head H0 = 60.0 mm of water column, coefficient a = 2.50 × 10−7 mm of water column per (Lpm)2 , available head Havailable is in units of mm of water column, and…
