PROPERTIES OF STEAM CLASS NOTES FOR MECHANICAL ENGINEERING Specific properties are per kg. Examples are specific volume, specific values of enthalpy, entropy, internal energy and latent heat. Symbol Small alphabets represent specific properties. Firstly specific volume =v Secondly specific enthalpy = h Thirdly specific entropy = s Fourthly specific internal energy =u Specific heat =cP…
STEAM CONDENSERS MULTIPLE-CHOICE QUESTIONS (MCQ) WITH ANSWERS MCQ on steam condensers increase the understanding about the working of condensers. Later, it helps in the design of condensers. Fig. Surface Steam Condenser Fig. Jet Steam Condenser A condenser condenses steam coming from the (a) Boiler (b) Super heater (c) Economizer (d) None ANS: (d) A condenser…
ENTROPY OF STEAM MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS Entropy is randomness. More is the randomness, more is the entropy. Every process in nature is ir-reversible. An ir- reversible process increases entropy. Increase of entropy means capacity to do useful work decreases. Entropy of water is zero at (a) -400C (b) -200C (c) +400C…
STEAM MULTIPLE CHOICE QUESTIONS (MCQ) WITH ANSWERS MCQ help to understand a topic in depth. It helps in the operation of a steam device. It helps in trouble shooting. Water consumes heat on rise of temperature (a) Latent heat (b) Enthalpy (c) Sensible heat (d) None ANS: © Water consumes heat without rise of temperature (a)…

ANS. S Turbine STEAM ENGINE & TURBINE CLASS NOTES FOR MECHANICAL ENGINEERING Steam engine works with steam made in the boiler. It converts heat energy of steam into mechanical motion. A steam engine uses Rankine cycle ( modified Carnot Cycle) and is thus…
STEAM CONDENSERS Vapor is converted into liquid by losing latent heat at the saturation temperature corresponding to a certain pressure. Condensers are used in steam engines, steam turbines of a thermal power station. Condensers are used in refrigeration and air conditioning plants too. Mostly shell and tube type condensers are used. In these condensers,…
STEAM NOZZLES CLASS NOTES FOR MECHANICAL ENGINEERING Turbines and steam engines use steam. Turbines produce electricity in thermal power plants. Turbines use nozzles to produce a high velocity jet. This jet runs the steam turbine. NOZZLES A nozzle is a passage of variable cross section. A nozzle produces high velocity jet. It converts (i)…
STEAM TURBINES QUESTION ANSWERS CLASS NOTES Question answers are very helpful in understanding and clarity about the topic. Fundamentals become well understood. Apply these in real life with ease. 1. What is a steam turbine? Steam turbine is a high speed rotating machine. It converts the heat energy of steam into work/motion/ electrical energy. 2….
STEAM JET REFRIGERATION CLASS NOTES FOR MECHANICAL ENGINEERING This refrigeration means refrigeration from heat. It uses a steam nozzle to create vacuum in the flash chamber. High vacuum causes water to evaporate and evacuate. Water vapors mix with high velocity steam jet. These are compressed in the diffuser. Mixture condenses in the condenser for recycling….
