Answer:
B.29
Explanation:
In general purpose acme thread:
Nominal depth of thread=0.5
Included angle =29 degrees
Generally Acme thread are following types
1.General purpose(G) Acme
2.Centralizing(C) Acme
3. Stub Acme
Centralizing(C) Acme threads have tighter tolerance during manufacturing as compare to General purpose(G) Acme threads.
Answer:
(c) an acme tool gage
Explanation:
with the help of an acme tool we measure the pitch of a screw thread it is used as reference for finding the pitch of the thread it is also called an inspection tool is aligned to work with an acme tool gage it is also used for gage the internal and external threaded product. it is also used for grinding and setting tools it is mainly work 29° thread angle
Answer:

Explanation:
The mixing chamber can be modelled by applying the First Law of Thermodynamics:

Since that mass flow rate of water at inlet 1 is the only known variable, the expression has to be simplified like this:

Besides, the following expression derived from the Principle of Mass Conservation is presented below:

Then, the expression is simplified afterwards:


Specific enthalpies are obtained from steam tables and described as follows:
State 1 (Superheated vapor)

State 2 (Saturated liquid)

State 3 (Liquid-Vapor mixture)

The ratio of the stream at state 2 to the stream at state 1 is:



The mass flow rate of the saturated liquid is:
