Question -7 . A horizontal steel pipe having inner and outer diameter as 150 and 180 mm respectively is lagged with 50 mm thickness of 85% magnesia insulation inside ,which has flue gas flowing at 260oc
Find out A - the heat loss per hour per meter run of pipe.B - the external surface temperature of lagging
Data given- Thermal conductivity of pipe and lagging = 44.64 &0.0576 w/m .oc respectively.Ambient air temperature =20oc Combined radiation and conductive external heat transfer co- efficient from outside surface to air =19.8 w/m2.oc The inside heat transfer film co- efficient = 22.7 w/m2.oc
Write a function called int_col that has one input argument, a positive integer n that is greater than 1,and one output argument v that is a column vector of length n containing all the positive integers smaller than or equal to n, arranged in suc..
The problem statement, all variables and given/known data A tube scanner made of a PZT piezoceramic material, which has a piezoelectric coefficient, d31=- 0.27x10 -9 mV -1 , has a length of 12.5 mm and wall thickness of 0.5 mm.
To be satisfactory quality the ratio of 'A' to 'B' in the mixture must be 100 to 1or higher. 'D' reacts with both 'A' and 'B' as follows;A + D?R-rA= 21 CACDB + D?S-rB= 147 CBCDAssuming that the reaction go to completion, how much 'D' need be added..
