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.

Answer:
A number of engine geometry properties and performance parameters obtained from dynamometer testing are given in Table below:
Please calculate:
i) Cylinder bore, bore to stroke ratio, connecting rod to crank radius ratio, and clearance volume in each engine cylinder.
ii) Brake power output at 3800 rpm and the torque output at 6000 rpm.
iii) Brake, indicated and friction mean effective pressures at both 3800 rpm and 6000 rpm.
iv) Brake specific fuel consumption in kg/(kW h) and brake thermal efficiency at 3800 rpm.
v) Volumetric efficiency at 3800 rpm.
vi) Air to fuel ratio and the relative air to fuel ratio at 3800 rpm. Is this a lean or rich mixture?

Explanation:
Answer:
A relief valve is either in the pressure reducer or in the downstream side of the system to ensure that the control air pressure does not exceed about 30 psig.
Answer:
Option A and C are correct.
Explanation:
First of all, a thermodynamic circle is closed and gotten when our starting and ending points are the same. Now, from the question, we can see that the water starts and ends on the same temperature and pressure. Thus, we can say that a thermodynamic circle has occurred. So, option A is correct.
Now, to achieve a reversible process, there should be no exergy losses could cause rise in exergy entropy. There are two possible causes which we cannot eliminate as both are useful. First is exergy friction while the second cause is heat exchange at different temperatures of heat reservoirs and our cube. This second cause is confirmed because our cube while melting is on lower temperature than it's surrounding. This causes rise in entropy in overall system, thus making the process irreversible. So option C is correct.
