is there any datasheet for how many end nodes can connect to the single Gateway! , need information ASAP.
Thanks in Advance
Directly no - as it will depend on the various nodes message length, on air time, Spreading Factor, Power level at receiver etc. in practical terms assuming a good distribution of SF’s most GW’s shoud be capable of supporting from 5-20k nodes, with upper limts anywhere from 30-50/60k nodes. If all the Nodes are only sending a short message (watchdog/keep alive - ‘I’m here, perhaps once per day or even once per week’) without any payload then its poss to get to very high numbers.
There was a tool kicking around years ago that allowed a simplistic simulation of # of nodes on a LoRa network but guess it is less applicable as networks are proliferating.
Remember where you say ‘connect’ to a given GW, this does not happen but understand you are really asking for capacity limits - the fact is LoRaWAN is a broadcast network with all messages in range of a given GW get detected and potentially handles and passed on to the back end NS - even if from an alien network and device addresses are not related to TTN or your own GW registered to TTN. Also if the local node environment demands lots of down links (Join Acks, Confirmed Packets, Return path Command & Control messages etc.) this can degrade reception capacity as the GW’s are simplex and cannot receive uolinks whilst sending downlinks…hence we try to limit downlinks through TTN FUP.
There are lots of academic papers on network capacity published (GIYF), with varying degrees of credibility if you go looking.

Hey,
I am Vinayak from IITB we are developing watermeter and we are using RN2483 to it. we have outdoor gateway (Kerl-Link). if we use 100+ end nodes(RN2483) to the single gateway will it work ?
1.time duration for RN2483 is 5min for testing and 6hr for real application.
2. Spread Factor is between SF8- SF10.
help ASAP.
Thanks in Advance
Short answer without a lot more info or details of the local RF environment is yes that should be well within capacity 
and is a classic use case for LoRa/LoRaWAN as evidenced by the number of water meters and press releases relating to Water Meter roll-outs that you can find if you apply your favourite search engine (Look at use cases/pr on the Semtech website as example)
Also this thread has been set up for the sharing of issues around setting up and running the various current and planned TTN communities vs addressing what are clearly technical questions or operational details of device/node/gw functionality therefore please limit further questions of this type in this thread
