This JSON captures Civil Engineering Paper II (Engineering Services Main) 2018. Page 1 provides exam header, duration, marks (300), language (English), and structure (two sections; answer five questions, with Q1 and Q5 compulsory). Page 2 presents Section A: Q1 with four subparts (a–d). Subparts cover hydraulic systems with two pipes in series, dimensional analysis via Pi numbers for a circular cylinder in flow, economical trapezoidal canal design, and a set of water treatment-related problems involving detention time, overflow rate, weir loading, river mixing with BOD/DO considerations, and sludge treatment concepts. The combined data enable SEO-ready metadata, topics, and FAQ generation.

Questions (page 2)
Q2. Q 1. (b) A circular cylinder is placed in a uniform flow with its axis perpendicular to the flow direction. The drag force on the cylinder per unit length, F_D, depends on the flow velocity, V, fluid density, ρ, fluid viscosity, μ, and the cylinder diameter, D. Obtain the non-dimensional sets (Pi numbers) which could be used to analyse this problem.
Q3.
Q
1. (c) Design a most economical trapezoidal canal section for carrying discharge of 45 cumecs and side slope of 1 1/2 : 1 at a velocity of 0.9 m/sec. Assume value of n = 0.022 (Manning's coefficient).
Q4.
Q
1. (d)
(i) A water treatment plant is to treat water at the rate of 6000 m3/day. If there are two rectangular sedimentation tanks (27 × 5 × 3.8 m) with total weir length of 50 m, determine
(i) Detention time; Overflow rate;
(ii) Weir loading. Q
1. (d)
(ii) A treatment plant disposes 50 MLD of treated effluent into a river. The river flow rate is 20 m3/s and its DO is 8 mg/L before the mixing point. If the BOD of the effluent is 50 mg/L, find the BOD and DO of the river water at the d/s of mixing point. Assume BOD of river water as 0 and DO in WW effluent as
0. Q
1. (d)
(iii) What is sludge and how is it classified? With the help of flow chart, explain different processes/operations involved in sludge treatment and indicate the objectives of each process/operation.
