hypothetical Q: If a centrifugal p/p driven by the engine (or any type of P/p)is fitted for fresh water cooling duties, how will it function when the engine is reversed? any ideas will help.. tvm

can somebody provide some info on microbial degradation of lube oil...sites...book sources etc.,? tvm

where can one find all the tests (coded by ASTM)for various Lubricating oils and Fuel oils? thanx

that is interesting! airborne and structure borne noises: are there any definite decibel level values for such noises? e.g., turbocharger noise, combustion noise, camshaft/poppet valve noises, crosshead slamming noises etc., any help on this? thanx.

One Drew Ameroid booklet says that Liquid Coagulant is not to be used in High Pressure boilers. any ideas on why? what other options are available for HP boilers? thanx.

thanx for the response. some doubts...when the engine is running(say a big marine diesel of @15000BHP, can we differentiate by ears the combustion noise? self had an experience in which a sharp noise(charactristic of mechanical fouling)in an engine of such size turned out to be from an airlocked...

1. each boiler requires atleast 1 safety v/v but if heating surface exceeds 500sq.ft then another v/v is required. also if the boiler is electric powered with power input >500kw, then more than 1 v/v is reqd. when more than 1 v/v of differing size is fitted then the relieving capacity of the...

are there any analytical methods to find the difference between combustion noise and mechanical noise in a diesel engine? under normal running what are the factors that indicate the noise emnating is from either of the sources? any parameters(frequency etc.,)? any ideas?

1.given a particular volume what are the factors to be considered for installing an axial flow blower or a c/fugal blower? 2. where exactly are axial flow fans used and why? 3. which application are c/fugal blowers used and why? 4. what is the difference in design considerations of a centrifugal...

can someone tell me the design factors involved in manufacture of air and oil filters?(e.g beta factor etc.,) any sites with basic info on filter types and design ? thanx.

i have found the info.. just sharing it now.. the following are used in the sprinklers: 1. an expanding liquid selected from the group consisting of toluene, a xylene, trichloroethylene, tetrachloroethylene and a mixture thereof. 2. lower monohydric aliphatic alcohol, a lower polyhydric...

help with these Qs,please! 1.what is the material of the bursting disc provided on the jackets of air compressors? 2.what are the materials used in the air side relief v/v? 3. what is the composition of fusible plugs and the ranges? thanx

can somebody provide info on the "special high expansion"liquid used in quartzoid bulbs of sprinkler systems?

can anyone explain in simple terms(mechanics) how an adjustable torque spanner or torque wrench works? thanx.

i ma repeating this from yet another forum because i got no response> Q: are there any chemical tests carried out on plates used for constructionof ships? what are the normal DT and NDT on materials used for ship construction and allowable standards for the same ? tahnx.
