PZX Numerical's basics and How to Solve | Nautical Class
Learn and understand about basics term that are required to solve PZX Numerical's. These numerical are very easy once you understand the basics and you are able to draw the correct diagram. One question is solved in the Video for understanding, many question will be solved in the next video.
Terms required to understand
Prime vertical -vertical circle passing through the East and West points of his rational horizon
Vertical circle -great circle on the celestial sphere passing through the observer’s Zenith and Nadir
Observer’s zenith -the point on the celestial sphere, vertically above the observer
Rational horizon -great circle on the celestial sphere, which is 90o away from his zenith
Zenith distance -is the arc of the vertical circle through that body contained between the rational horizon and the centre of the body
Declination -is the arc of a celestial meridian or the angle at the centre of the Earth, between the equinoctial and parallel of declination through that body
Amplitude -is the arc of the observer’s rational horizon or the angle at his zenith between the observer’s prime vertical and the vertical circle through the body
Azimuth -is arc of the observer’s rational horizon or the angle at his zenith between the observer’s celestial Meridian and the vertical circle through that body
True altitude - is the arc of the vertical circle through that body contained between rational horizon and the centre of the body
These Numerical's can be solved mostly using Napier's Formula or Cosine Formula.
Kindly watch the full video to understand how to use these formula.

Basic Cargo Calculation using ASTM Table -Tanker | Nautical Class
มุมมอง 35K4 ปีที่แล้ว
Learn the basic about Cargo Calculation using ASTM Tables. Understand the Terms required for Calculation Total Observed Volume (TOV) - is the volume of oil including total water and total sediment measured at the observed oil temperature. Gross Observed Volume (GOV) - is the volume of oil including dissolved water, suspended water and suspended sediment but excluding free water and bottom sedim...
Kindly post some more video like this. Bro 👏
Very informative video, one sugggestion make your curser visible on the screen at all times so that we know where it is moving.
OBSERVED VALUE OF DENSITY AT 15 DEG C BY CONVERTING USING ASTM TABLE 53 B IS VACCUM OR AIR??
@23:14 mass is wrong calct'd
Yeah I saw that too..
Wasted 25:45 mins of my life. Worst explanation ever. No concepts were clear. Highly not recommended for 2MFG guys.
Writing is very fade please dark it Little faster Thank you for this
Density in 54A/B is Vac or in Air ?
Vac
Thanks sir, Laboratories are measure density by hydrometer in atmosphere then why considering lab density in vaccum..
Thanks a lot for your job.Very well explained.Your video helps me very much
Good day why is it that you didn't use table 53 A but you rather use table 54 B
Very helpful for 2nd mates
Best video ever on pzx triangle 💐⚓
Thank you. Keep watching and share with your friends!
Very helpful, thanks for the video, plz make more also
Very useful
Thanks a lot bro best video on pzx 👍
Keep Watching
Very nicely explained sir
Sir, Excuse me, I have a question about this theoretically: What is the latitude of a place where the length of the day is 2/5 the length of the night if the sun's declination is 20 degrees 20 mins south?
Tremendously elaborated and understood well, However, please do mention if yu ve done some pzx triangle video with cosine formula. Where we do not have 90° in our questions
Excellent ! Thank you sir !
plz solve may 2012 question???????
sir please upload other topic also.
Very good video... Thanks for making
I can't imagine you made it to me so simple thanks for sharing your knowledge in well planned manner.

Very nice and well explained video. Please do a video on making stowage plan once we receive orders on tankers. Please make it soon
Thank You for your response. Have considered your request will prepare a video on making stowage plan. Keep watching and supporting.

Hi can you pls do a vcf calculation for a tank Rail car ..
Hello Cristopher, VCF (Volume Correction Factor) is for the volume of liquid in any containment system. Once you have the observed volume in rail car further calculation will be same as explained in the video.
brother..how come if lat is 43 deg 39S and dec is S 66 deg 47min...both same name and addition is more than 90Deg....you did not make circumpolar in the diag???? i mean the celestial body diag was rising n setting the observer rational horizon???? hows that posibble bro>
Keep update all the time sir thank you for sharing your knowledge..
Really Nice...it helped me a lot...hardwork can be seen...keep up the good work...
Good morning friend For preparation of second mate / DNS/ BSC nautical science/NCV come in #kundanpatna
Exactly what i needed <3 ... keep making these videos....
Glad to hear that!

How do you define the thievage?
very well done, but guys if you want to understand it in detail, go to oil cargo calculations HIMT , you will get a better idea.

Very well explained sir 👌👌
Excellent explanation...thanks
Very informative video for all the cadets appearing for exams 🔥🔥
Very nice , calm and understanding manner used to explain the topic...
Good morning friend For preparation of second mate / DNS/ BSC nautical science/NCV come in #kundanpatna
Nyc content very informative!!!
please put with subtitles in Portuguese, I need this video too much
Thank you sir
Excellent, Keep it up
Very well explained Nd helpful to all seafarers.
Superb content very helpful 🔥🔥🔥🔥🔥
asnesh sawant thank you
