Answer:
Corps regulators now send threatening letters to farmers who switch from one crop to another, such as rice to orchards, or perform routine plowing.
Explanation:
The Corps says the farmers can be performing a “land-use” change that suddenly puts a farm under Corps jurisdiction. It is getting harder and harder, and in legal terms more dangerous, to be an American farmer these days, thanks to the aggressive behavior of the federal Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers. Increasingly, those regulations are changing at the arbitrary say-so of the Corps regulators who implement the EPA’s regulations on the ground, even though most practices followed by American farmers have been exempted from CWA prohibitions since it was written in 1977.
Answer:
a) 4.1 kw
b) 4.68 tons
c) 4.02
Explanation:
Saturated vapor enters compressor at ( p1 ) = 2.6 bar
Saturated liquid exits the condenser at ( p2 ) = 12 bar
Isentropic compressor efficiency = 80%
Mass flow rate = 7 kg/min
A) Determine compressor power in KW
compressor power = m ( h2 - h1 )
= 7 / 60 ( 283.71 - 248.545 )
= 4.1 kw
B) Determine refrigeration capacity in tons = m ( h1 - h4 )
= 7/60 ( 248.545 - 107.34 )
= 16.47 kw = 4.68 tons
C) coefficient of performance ( COP )
= Refrigeration capacity / compressor power
= 16.47 / 4.1 = 4.02

OLAP (online analytical processing) software is the software to perform various high-speed analytics of large amounts of data from a data center, data mart, or other integrated, centralized data store.
<h3>What is the use of Online Analytical Processing (OLAP)?</h3>
OLAP provides pre-calculated data for various data mining tools, business modeling tools, performance analysis tools, and reporting tools.
OLAP can help with Planning and Budgeting andFinancial Modeling. Online Analytical Processing (OLAP) is included in many Business Intelligence (BI) software applications. It is used for a range of analytical calculations and other activities.
Therefore, OLAP (online analytical processing) software is the software to perform various high-speed analytics of large amounts of data from a data center, data mart, or other integrated, centralized data store.
