Lab 2 : Flow Measurements

Assalamualaikum, my name is Muhammad Al-Hasyir bin Mohd Wazir(13DEM19F1021). Today I will explain about experiment 2 : Flow Measurements,



Apparatus
  1. Hydraulic bench
  2. Stop watch
  3. Screw driver or pen
  4. SOLTEQ Flowmeter Measuring Apparatus



Experimental Procedures
  1. Fully close the control valve and fully open the discharge valve.
  2. Ensure the discharge hose properly directed to sump tank. Also ensure the collection tank drain hole is open to allow flow discharge back into sump tank.
  3. Fill sump tank with 3/4 full of water.
  4. Start up the pump supply.
  5. Slowly, open the control valve until its approximately half open.
  6. At this point, water flowing from sump tank to the flow apparatus and discharge through into collection tank.
  7. Wait until there is no trapped bubble in the system.
  8. Adjust the discharge and control valve until rotameter reach desire reading.
  9. By using the air bleed screw ( staddle valve ) , adjust water level in the manometer board ( using screwdriver or pen ). Retain maximum readings on manometers with the maximum measurable flow rate.
  10. Note readings on manometers (A and C).
  11. Close the collection tank drain hole.
  12. Look at volume gauge. Start the stopwatch until volume gauge reach 5L and stop the stopwatch until the volume reach 10L.Note the stopwatch reading.
  13. Open collection tank drain hole.
  14. Step 8-13 repeat for other 3 readings.


This is formula that we used to calculated the Venturi Meter Flowrate

Thats all from me, Thank you : )

SUPERHEATED STEAM

Assalamualaikum warahmatullahi wabarakatu kepada semua Rakan-Rakanku dan Pensyarah-Pensyarah yang dirahmati Allah sekalian.                Saya wakil pelajar dari  POLITEKNIK SULTAN MIZAN ZAINAL ABIDIN(PSMZA) dari kelas DEM2S1 yang bernama KHAIRUL DANISHAHMI BIN KHAIRULNIZAM a.k.a Keyoo dan saya adalah pelajar semestar 2 sesi Dis 2019 dalam bidang Diploma Kejuruteraan Mekatronik(DEM).Saya telah diberikan tugasan untuk membuat rumusan yang bertajuk SUPERHEATED STEAM pada minggu ini.So gais,korang mesti tak pernah dengar apa itu Superheated Steam kan?Meh sini saye ceritakan sikit.          Okay,Superheated Steam adalah suatu bentuk stim pada suhu yang lebih tinggi dari titik mendidihnya.Ia adalah keadaan yang relatif kepada sesuatu yang dipanggil tepu atau basah dan wap.Wap jenis ini adalah yang hanya melebihi titik didih sumber pada tekanan tertentu.          Untuk memahami bagaimana ai...

BAB 2: FLUID APPLICATION PART 1

       BAB 2 : FLUID APPLICATION PART 1 Assalamualaikum w.m.t              Saya  FARAH HAZIQAH AUNI BINTI FAIZAL 😘 wakil pelajar dari kelas DEM2A1 di  POLITEKNIK SULTAN MIZAN ZAINAL ABIDIN  yang terletak di Terengganu. Saya ingin menceritakan tentang hukum paskal dan jek hydraulik. PRINSIP DAN HIDRAULIK PASKAL 💙 Prinsip paskal menyatakan bahawa tekanan yang dikenakan keatas sesuatu cecair boleh dipindahkan  ke seluruh cecair itu dengan seragam. prinsip paskal juga dikenali sebagai prinsip pemindahan cecair dalam cecair. prinsip pemindahan tekanan dalam cecair digunakan dalam sistem hidraulik.sistem hidraulik menggunakan cecair yang tidak dikompresikan seperti minyak atau air untuk menghantar kuasa dari satu lokasi ke lokasi yang lain dalam bendalir.                             apabila ombok ditolak kedalam sfera bulat, air ...

CONCEPTUAL PRINCIPLE OF THERMOFLUIDS.      First and foremost. I would like to introduce myself who create this discussion. My name is Muhammad Amirul Putra Bin Adnan and I'm currently studying at Politeknik Sultan Mizan Zainal Abidin in Terengganu. I'm the chosen one to discuss this topic by being the representative for Mechatronic Engineering students class of June 2019 session from DEM2S1. This task was handed by Mr. Roshaizul Nizam Bin Sani.                        1.5 : Definition of system, boundary, surrounding, open system and close system. System:       By my observation, thermodynamic system or even shortened known as system is a fluid contained by the cylinder head, cylinder walls and the piston. These objects or materials will produce work that we could say it as a system to be more precise. Boundary:       Boundary is like a wall around system to keep...
