How many teeth of taper tap bottom are chamfered? Correct Answer 1 to 2

Explanation:

Chamfer Tap

  • A general name for taps containing threads at the front end of the land that are cut away and relieved at the crest of the first sew teeth.
  • The purpose of this modification is to allow easier starting by distributing the cutting action over several teeth as the threads are being cut. 
  • When the tapering amounts to 7 to 10 threads, the tap is called a taper tap.
  • When the tapering amounts to 3 to 4 threads, the tap is called a plug tap.
  • When the tapering amounts to 1 to 2 threads, the tap is called a bottoming tap.

Given below are quantities named A,B and C. Based on the given information, you have to determine the relation between the quantities. You should use the given data and your knowledge of mathematics to choose among the possible answer. Quantity A: Tap1 and Tap2 can fill the tank in 16 hours and 25 hours respectively. Both the taps opened together. After some time Tap 1 is closed and after that the tank is filled in 12 hours. In how many hour Tap 1 and 2 work together? Quantity B: Three taps 1, 2, 3 can fill a cistern in 10,14,18 hours respectively. If tap 1 is kept open all the time and tap 2 and 3 is opened alternatively for an hour then find in how many hours the tank will be filled? Quantity C: Two taps 1 and 2 are such that tap 1 fills the tank in 10 hours and tap2 empties it in 20 hours. If tap 1 is opened first and after 5 hours tap 1 is closed and tap 2 is opened, then the tank emptied in x hours and find the value of x?
The following questions have three statements. Study the question and the statements and decide which of the statement(s) is/are necessary to answer the question. In how many hours tap B can fill the completely empty tank? Statement I: The inlet tap A and the outlet tap C working simultaneously takes 40 hours to fill the tank. Statement II: Efficiency of inlet tap B is equal to efficiency of outlet tap C or 62.5% of the efficiency of inlet tap A. Statement III: The outlet tap C can empty a half filled tank in 12 hours.
In a public bathroom there are n taps 1,2,3...n. Tap1 and Tap2 take equal time to fill the tank while Tap3 takes half the time taken by Tap2 and Tap4 takes half the time taken by Tap3. Similarly each next number of tap takes half the time taken by previous number of Tap i.e, K-th Tap takes half the time taken by (K-1)th Tap.If the 10th tap takes 2 hours to fill the tank alone then what is the ratio of efficiency of 8th tap and 12th tap, respectively?
Select the correct alternative from the given choices. Tap A can fill a cistern in 12 hours and tap B can fill the same cistern in 8 hours while tap C can empty full cistern in 10 hours. Tap A started at 9 a.m. and tap B started at 11 a.m. At what time tap C should be started such that the cistern will be half full at 1 pm?
Tap A can fill the water cooler in 20 minutes and Tap B can fill water cooler in 1 hour. Tap A is alone opened for 10 minutes. After 10 minutes, tap B is alone opened for 20 min. After this both taps are opened for 2 minutes, then tap B is closed. In what time remaining water cooler is completely filled by tap A?
A tank is filled by three taps A, B and C with uniform flow. Tap A and B operating simultaneously fill the tank in the same time during which the tank is filled by tap C alone. Tap B fills the tank 5 hours faster than tap A and 4 hours slower than Tap C. The time required by the Tap C is:
Tap A alone can fill the tank in 30 hours while tap B alone can fill the tank in 12 hours. Tap C empties the filled tank. When all three taps are opened then the tank gets emptied in 20 hours. In what time the tank gets emptied when Tap C is opened after 1/4th of the tank is filled by tap A and tap B?
There are 2 taps connected to a bucket. One tap flow hot water and other tap flow cold water. Hot water tap can fill the bucket in 15 min and cold water tap can fill the bucket in 10 min. A person opened both the tap and left the place. He returned at the time when bucket should be full but he found that due to leakage in the bottom of bucket. It is yet to be full. He reported the leakage and bucket become full in 2 minutes more, in how much time leakage can empty the bucket alone?
