Answer:
The architectural pattern i will use for the school management is the client-server pattern.
This pattern would consist of a server and many clients. wherein the server component would provide services to that of the clients and its components as specified and also there would be a client request service from that of the server.
Explanation:
Solution
A school management system would always involve the client server pattern as this pattern would have a server and many clients wherein the server component would give services to that of the clients and its components as specified and also there would be a client request service from that of the server. This server would share the appropriate services to such clients and also listen to the client's requests.
Such kind of pattern would mostly be used for for the online platforms or application like that of document.
Answer:
The maximum water pressure at the discharge of the pump (exit) = 496 kPa
Explanation:
The equation expressing the relationship of the power input of a pump can be computed as:
![E _{pump,u} = \dfrac{m(P_2-P_1)}{\rho}](https://tex.z-dn.net/?f=E%20_%7Bpump%2Cu%7D%20%3D%20%5Cdfrac%7Bm%28P_2-P_1%29%7D%7B%5Crho%7D)
where;
m = mass flow rate = 120 kg/min
the pressure at the inlet
= 96 kPa
the pressure at the exit
= ???
the pressure
= 1000 kg/m³
∴
![0.8 \times 10^{3} \ W = \dfrac{(120 \ kg/min * 1min/60 s)(P_2-96000)}{1000}](https://tex.z-dn.net/?f=0.8%20%5Ctimes%2010%5E%7B3%7D%20%5C%20W%20%3D%20%5Cdfrac%7B%28120%20%5C%20kg%2Fmin%20%2A%201min%2F60%20s%29%28P_2-96000%29%7D%7B1000%7D)
![0.8 \times 10^{3}\times 1000 = {(120 \ kg/min * 1min/60 s)(P_2-96000)}](https://tex.z-dn.net/?f=0.8%20%5Ctimes%2010%5E%7B3%7D%5Ctimes%201000%20%3D%20%7B%28120%20%5C%20kg%2Fmin%20%2A%201min%2F60%20s%29%28P_2-96000%29%7D)
![800000 = {(120 \ kg/min * 1min/60 s)(P_2-96000)}](https://tex.z-dn.net/?f=800000%20%3D%20%7B%28120%20%5C%20kg%2Fmin%20%2A%201min%2F60%20s%29%28P_2-96000%29%7D)
![\dfrac{800000}{2} = P_2-96000](https://tex.z-dn.net/?f=%5Cdfrac%7B800000%7D%7B2%7D%20%3D%20P_2-96000)
400000 = P₂ - 96000
400000 + 96000 = P₂
P₂ = 496000 Pa
P₂ = 496 kPa
Thus, the maximum water pressure at the discharge of the pump (exit) = 496 kPa
Answer:
Hand tools based on job requirement and its importance and the classification of hand tools according to its function and its importance are discussed below in details.
Explanation:
Hand tools based on work requirement is essential because Every tool is specifically invented for a particular purpose, so picking the accurate tool will also reduce the amount of energy needed to get work done right without causing injury or harm to either the tools or the exterior being worked on.
classifying of hand tools: wrenches, screwdrivers, cutters, striking tools, hammer tool or struck, pliers, vise, clamps, snips, saws, drills, and knives.
