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?
Sumit takes out water in a beaker from a bucket for an experiment. He puts the thermometer in the water in beaker and notes the reading as 35°C. Which of the following conclusions drawn by him are correct? A. The temperature of water in beaker and bucket are almost same. B. The heat in water in beaker and bucket are same C. The temperature of water in beaker is less than the temperature of water in bucket. D. The heat in water in bucket is more than the heat in water in beaker
In a race, a competitor has to collect 6 apples which are kept in a straight line on a track and a bucket is placed at the beginning of the track which is a starting point. The condition is that the competitor can pick only one apple at a time, run back with it and drop it in the bucket. If he has to drop all the apples in the bucket, how much total distance he has to run if the bucket is 5 meters from the first apple and all other apples are placed 3 meters apart?
A bucket is in the form of a truncated cone. The diameters of the base and top of the bucket are 6 cm and 12 cm respectively. If the height of the bucket is 7 cm, what is the capacity of the bucket?
Statement 1: Bucket conveyors can be divided into close and spaced bucket conveyors. Statement 2: Bucket conveyors can be divided into centrifugal and positive discharge bucket conveyors.
Water, having a density of 1000 kg/m3, leave from a nozzle with a velocity of 10 m/s and the jet strikes a bucket mounted on a Pelton wheel. The wheel rotates at 10 rad/s. The mean diameter of the wheel is 1 m. The jet is split into two equal streams by the bucket, such that each stream is deflected by 120°, as shown in the figure. Friction in the bucket may be neglected. Magnitude of the torque exerted by the water on the wheel, per unit mass flow rate of the incoming jet, is
Consider the relational schema given below, where eId of the relation dependent is a foreign key referring to empId of the relation employee. Assume that every employee has at least one associated dependent in the dependent relation. Employee (empId, empName, empAge) Dependent(depId, eId, depName, depAge) Consider the following relational algebra query: ΠempId(employee)-ΠempId (employee⋈(empId = eID)∧(empAge ≤ depAge)dependent) The above query evaluates to the set of empIds of employees whose age is greater than that of
A bucket wheel excavator with 20 buckets of capacity 0.5 m3 each, rotates at 5 rev/min. The bucket fill factor is 80%. The excavator loads on to 1200 mm wide belt conveyor. The cross-section area (m2) of the material on the belt is 0.1B2, where B is the belt width in m. The minimum speed of the belt in m/s to avoid spillage of material is
গরম বাতাসে পরিপূর্ণ M ভরের একটি বেলুন (থ্রডি সহ) পৃথিবীর দিকে খুব ত্বরণ a তে নেমে আসছে। ঝুড়ি থেকে কি পরিমান m ভর ফেলে দিলে বেলুনটি উপরের দিকে একই খুব ত্বরন a- তে উঠে যাবে ? সকল ক্ষেত্রে বেলুনটির আয়তন একই ছিল বলে ধরে নেওয়া হলো। (g = অভিকর্ষীয় ত্বরন)(A hot air balloon with a bucket is descending towards the earth with a constant acceleration a. The combined mass of the balloon and bucket is M. What mass m from the bucket should be released so that the balloon starts ascending up with the same acceleration a? Consider the volume of the balloon remains constant at all the time. (g=acceleration due to gravity))
